After controlling for the

The authors conducted extensive tests for the robustness of this finding, all of which it passed. Their main conclusion is worth quoting in full: This meta-analysis of published and unpublished data provided clear answers to our three questions. First, studies from the United States supported a moderately sized Gene × SES

of articles that Maccoby and Jacklin had underestimated the role of differential socialization (e.g., Block (1978), Block (1983)). Lytton and Romney (1991), a subsequent meta-analysis of 172 studies of gender socialization, examined socialization regarding eight topics: amount of interaction, achievement encouragement, warmth, nurturance, responsiveness (including praise), encouragement of dependency,

restrictiveness/low encouragement of independence, disciplinary strictness, encouragement of sex-typed activities, sex-typed perception, and clarity of communication/use of reasoning. The meta-analysis found few differences on any of them. “The effect sizes for most socialization areas are nonsignificant and generally very small, fluctuating in direction across studies

circulate). Boldt’s faked results made it look as if hydroxyethyl starch was safe for this purpose, a verdict bolstered by the fact that a ‘meta-analysis’ – a review study that pools together all the previous papers on the subject – reached the same conclusion. This was only true, however, because Boldt

’s fraud hadn’t yet been revealed; the meta-analysis included his fake results as part of its review. When Boldt’s deception became known, and his papers were excluded from the

of publication bias when we zoom out to look at a whole segment of scientific literature. This zooming-out often takes the form of a meta-analysis, which by combining results from multiple studies can calculate the overall effect (sometimes, perhaps tempting fate, called the ‘true’ effect) on a given topic.

random fluctuations caused by error should cancel out across different samples – the overall effect size calculated in a meta-analysis is normally considered more reliable than the estimates from individual studies. A meta-analysis doesn’t calculate the overall effect simply by averaging the effect sizes reported by all the included studies. It

more limited snapshots and are more affected by sampling error, will have more variability, over- and under-estimating the true effect by wider margins. A meta-analysis therefore gives more weight to the effect sizes from big studies, because they’re likely to be more accurate.28 In the context of publication

one dot per study, you’d expect your graph to look something like Figure 2A below. (Note that this is an idealised version of a meta-analysis; real datasets almost never look this clear-cut.) Looking at this ‘funnel plot’ (so named for what are hopefully obvious reasons), you can see

funnel shape is just what we’d expect if all the studies had converged upon a real effect. Figure 2. Funnel plots from an imaginary meta-analysis, in two different scenarios. In scenario A, the distribution of the thirty studies is about what you’d expect if every study ever done

The vertical line in the middle of each graph is the overall effect size calculated by each meta-analysis. In the case of scenario B, it’s been shifted to the right, meaning that the meta-analysis is coming up with a bigger effect than it should. Just as in an archaeological dig,

a lack of weapons might mean they were civilians rather than soldiers – we can learn a lot from what we don’t see in a meta-analysis. What if our plot looks more like Figure 2B? Here, we’ve lost a chunk from the expected shape. The studies we’d expect

that fits our pre-existing beliefs and desires), is what’s at the root of publication bias. If you consider the overall conclusions of a meta-analysis based on Figure 2B rather than 2A, you can see how publication bias deranges the scientific literature. If the studies with small effects have

been removed from the funnel shape, the overall effect that shows up in the meta-analysis will by definition be larger than is justified. We get an exaggerated view of the importance of the effects and can be misled into believing

or ambiguous studies, researchers force blinkers onto anyone who reads the scientific literature. One of the most striking recent funnel plots was featured in a meta-analysis by the psychologist David Shanks and his colleagues.29 It examined yet another variation on the priming theme: ‘romantic priming’. This is the idea that

However, when those studies were plotted for the meta-analysis, the funnel had a huge chunk missing: compelling evidence that many of the studies that hadn’t found the effect had been nixed prior to

have weird shapes for reasons other than publication bias, especially if there are a lot of differences between the assorted studies that go into the meta-analysis.36 There are many cases where publication bias is more subtle, and thus harder to discern, than in those described above. Are there better

analyses we covered earlier. Even leaving aside the fact that some research is often missing due to publication bias, if the studies included in the meta-analysis are all themselves exaggerated by p-hacking, the overall combined effect – in what’s supposed to be an authoritative overview of all the knowledge on

powerful forces that affect individuals and shape society. The evidence for the phenomenon is quite weak, and possibly subject to publication bias, for a 2015 meta-analysis reviewing all the relevant stereotype threat studies found a clear gap where the small, null studies on the subject – those that showed girls were equally

more unsaturated ones. This is a cornerstone of nutritional advice, repeated in countless dietary guidelines.95 But it didn’t hold up in a 2017 meta-analysis that compared saturated fatty acids to polyunsaturated fatty acids for their effects on heart disease and death.96 This was probably for three reasons. First

Third, many trials were designed incompetently, with changes in factors other than the diets that could have affected their results.99 The conclusion of the meta-analysis was that there was little compelling evidence for the benefits of replacing saturated with unsaturated fat, and that previous meta-analyses – the ones on which

Logo. You may have worked out by now that anyone who is thinking about doing a clinical trial of an intervention should first do a meta-analysis of all the previous trials on that same intervention. In practice, researchers only occasionally do this. Dean Fergusson and colleagues of the Ottawa Health

Research Institute published a cumulative meta-analysis of all randomised controlled trials carried out on the drug aprotinin in peri-operative bleeding during cardiac surgery [16]. They lined up the trials in

the research communities. The beneficial effect of aprotinin reached statistical significance after only 12 trials—that is, back in 1992. But because nobody did a meta-analysis at the time, a further 52 clinical trials were undertaken (and more may be ongoing). All these trials were scientifically unnecessary and unethical (because half

A χ2 value much greater than the number of trials in a meta-analysis tells us that the trials that contributed to the analysis are different in some important way from one another.

of research into homeopathy in order to develop an over-arching conclusion that took into consideration each and every trial. This is known as a meta-analysis, which means an analysis of various analyses. In other words, each individual trial into homeopathy concluded with an analysis of its own data, and Linde

was proposing to pool all these separate analyses in order to generate a new, more reliable, overall result. Meta-analysis can be considered as a particular type of systematic review, a concept that was introduced in the previous chapter. Like a systematic review, a

meta-analysis attempts to draw an overall conclusion from several separate trials, except that a meta-analysis tends to involve a more mathematical approach. Although the term meta-analysis might be unfamiliar to many readers, it is a concept that crops up in

single poll, because the meta-poll (i.e. poll of polls) reflects the complete data from a much larger group of voters. The power of meta-analysis becomes obvious if we examine some hypothetical sets of data concerning astrology. If your astrological sign determined your character, then an astrologer should be able

one way to interpret these sets of data would be to conclude that, in general, the experiments support astrology. However, a meta-analysis would come to a different conclusion. The meta-analysis would start by pointing out that the number of attempts made by the astrologer in any one of the experiments was relatively

could be explained by mere chance. In other words, the result of any one of these experiments is effectively meaningless. Next, the researcher doing the meta-analysis would combine all the data from the individual experiments as though they were part of one giant experiment. This tells us that the astrologer had

.98 out of 12, which is very close to 1 out of 12, the hit rate expected by chance alone. The conclusion of this hypothetical meta-analysis would be that the astrologer has demonstrated no special ability to determine a person’s star sign based on their personality. This conclusion is far

more reliable than anything that could have been deduced solely from any one of the small-scale experiments. In scientific terms: a meta-analysis is said to minimize random and selection biases. Turning to medical research, there are numerous treatments that have been tested by

meta-analysis. For example, in the 1980s researchers wanted to know if corticosteroid medication could help reduce respiratory problems in premature babies. They designed a trial which

each individual trial varied from hospital to hospital, because the numbers of babies in each trial was small and random influences were large. Yet a meta-analysis of all the trials showed with certainty that corticosteroid medication during pregnancy benefited premature babies. This treatment is part of the reason why the number

syndrome has fallen dramatically – there were 25,000 such deaths in America in the early 1950s and today the number is fewer than 500. The meta-analysis in the premature baby study was fairly straightforward, because the individual trials were similar to each other and so they could be merged easily. The

same is true of the hypothetical example concerning astrology. Unfortunately, conducting a meta-analysis is often a messy business, because the individual trials have generally been conducted in different ways. Trials for the same medication might vary according to

the dose given, the period of monitoring, and so on. In Linde’s case, the meta-analysis was particularly problematic. In order to draw a conclusion about the efficacy of homeopathy, Linde was attempting to include homeopathy trials investigating a huge variety

homeopathic conferences, contacted researchers in the field and eventually found 186 published trials on homeopathy. He and his colleagues then decided to exclude from his meta-analysis those trials that failed to meet certain basic conditions. For example, in addition to a group of patients being treated with homeopathy and a control

weight in the overall conclusion, because the reliability of a trial’s result is closely linked to the number of participants in the trial. The meta-analysis was eventually published in September 1997 in the Lancet. It was one of the most controversial medical research papers of the year, because its conclusion

were much more likely to show signs of improvement than those patients in the control groups receiving placebo. The paper concluded: ‘The results of our meta-analysis are not compatible with the hypothesis that the clinical effects of homeopathy are completely due to placebo.’ In other words, according to the

meta-analysis, homeopathy was genuinely effective. Not surprisingly, Linde’s conclusion was questioned by opponents of homeopathy. Critics argued that his meta-analysis had been too lax, inasmuch as it had included too many trials of relatively poor quality

is a good indication of their overall level of rigour. Critics pointed out that sixty-eight out of the eighty-nine trials in Linde’s meta-analysis scored only 3 or less on the Oxford scale, which meant that three-quarters of the trials were substandard. Moreover, critics pointed out that restricting

the meta-analysis to the higher-quality trials (4 or 5 points) drastically reduced the apparent efficacy of homeopathy. In fact, the conclusion of the twenty-one higher

was clear evidence that studies with better methodological quality tended to yield less positive results.’ Then, referring back to the original meta-analysis, he stressed: ‘It seems, therefore, likely that our meta-analysis at least over-estimated the effects of homeopathic treatments.’ Linde’s original 1997 paper had supported homeopathy, yet his revised 1999

paper was much more equivocal. His re-analysis of his own meta-analysis obviously disappointed the alternative medicine community, yet it was also frustrating for the medical establishment. Everyone was dissatisfied because Linde was neither able to claim

scrutiny from the late 1990s onwards. This eventually prompted Dr Aijing Shang and his colleagues at the University of Berne, Switzerland, to undertake a fresh meta-analysis of all the trials published up to January 2003. The medical research group at Berne, which is led by Professor Mathias Eggers, has a world

-wide reputation for excellence and the Swiss government had provided the team with adequate funding for a fully rigorous meta-analysis. Hopes were high that Shang would at last be able to deliver a reliable conclusion. Indeed, after two centuries of bitter dispute between homeopaths and

mainstream medics, Shang’s meta-analysis was destined to decide, at last, who was right and who was wrong. Shang was ruthless in his demand for quality, which meant that his

meta-analysis included only those trials with large numbers of participants, decent blinding and proper randomization. In the end, he was left with only eight homeopathy trials.

After studying the data from these eight trials – the best available trials on homeopathy – his meta-analysis reached its momentous conclusion. On average, homeopathy was only very marginally more effective than placebo. So, did this tiny marginal average benefit suggest that homeopathy

his conclusion was wholly compatible with the judgement that homeopathy acted as nothing more than a placebo. In fact, the most sensible interpretation of the meta-analysis was that homeopathy was indeed nothing more than a placebo. This interpretation becomes more convincing if we bear in mind another aspect of his research

. While conducting his meta-analysis on homeopathy, he also conducted a meta-analysis for a whole variety of new, conventional pharmaceuticals. These pharmaceuticals had been tested on the same illnesses that had been considered for

the homeopathy meta-analysis. In this secondary meta-analysis, Shang scrupulously applied exactly the same selection criteria to these conventional drug trials as he had done in his homeopathy meta-analysis. The

result of his meta-analysis on conventional drug trials was that on average they worked. Although

body. This illustrates the stark difference between pseudo-medicine and real medicine. Shang published his results in the Lancet in August 2005. Based on his meta-analysis, he concluded: ‘This finding is compatible with the notion that the clinical effects of homeopathy are placebo effects.’ Reinforcing this point, the Lancet ran an

about homeopathy’s lack of benefit’. This sparked major news stories around the world, angering homeopaths who refused to accept the conclusions of Shang’s meta-analysis and the Lancet’s accompanying statement. They attempted to undermine the research by pointing out four key issues, but in fact each of their criticisms

can be easily addressed. Homeopaths might argue that Shang’s paper indicates a positive effect for homeopathy, and that his meta-analysis therefore supports homeopathy. There is indeed a positive effect for homeopathy, but it is very small and entirely compatible with the treatment being a placebo

offers any benefit beyond placebo. Homeopaths claim that Shang dredged the data, which means that the meta-analysis was conducted in such a way as to bias the conclusion. There are indeed many ways to conduct a meta-analysis. Therefore it is possible to ‘dredge the data’ in different ways until the most positive

or negative result emerges, but importantly Shang had stated what his approach would be before embarking on the meta-analysis, and his approach seemed reasonable and unbiased. In other words, the research was impartial because the goalposts were decided before the data was examined, and

the goalposts were of a fair size and were not moved once the research was under way. Homeopaths point out that the meta-analysis included trials for several illnesses, which makes it too crude to say anything meaningful about homeopathy’s ability to treat individual conditions. This over-arching

meta-analysis was prompted by the fact that there has been no convincing evidence that homeopathy can treat any individual condition. Whenever researchers have conducted systematic reviews

and over again there were tantalizing indications that St John’s wort was more than a mere placebo. The next step was to perform a meta-analysis, whereby all the data from all the trials would be carefully brought together in order to get a firmer grasp of the true value of

the plant. The first meta-analysis of St John’s wort was conducted in 1996 and included the results from twenty-three studies. Referring to St John’s wort by its

of publicity, sales of St John’s wort in America increased by a factor of 30 in just three years. The conclusion of the 1996 meta-analysis was reinforced in 2005 by the Cochrane Collaboration. It conducted a systematic review entitled St John’s wort for depression, which covered all the thirty

constant field strength rather than fluctuating strength – magnets relates to pain control. Researchers at Exeter University recently included nine placebo-controlled, randomized trials in a meta-analysis. The results do not support the use of static magnets for pain relief. For other problems, such as menstrual symptoms or varicose veins, the evidence
