To understand a meta‐analysis, best read the fine print

The results of a meta-analysis are more than just the reported odds ratio, 95% confidence interval (CI), and p value. Of equal importance is the fine print of the study which should include assessment of the risk of bias, certainty in evidence, and heterogeneity in the individual point estimates and CIs. These areas all have an influence on the quality of the data in the analysis. Reading and understanding the fine print is important.
