I would like to discuss point 15 on page 342: ‘When the same hypothesis is tested in different studies and none or a minority of the tests are statistically significant (all P > 0.05), the overall evidence supports the hypothesis.’ While individual studies may not show statistical significance, it would be incorrect to assume that this trend applies to all studies. For example, in a meta-analysis that combines various studies with no statistical significance or conflicting findings, evidence of an effect may emerge, possibly due to an increase in sample size.
