What is it about?
This study compares several methods that can be used to examine whether a meta-analysis is affected by publication bias.
Why is it important?
Publication bias is a common threat in meta-analysis and may, for instance, occur when studies are more likely to be published if their results are statistically significant. If the presence of publication bias is ignored, summary results (e.g. treatment effects) are usually too extreme and can therefore be highly misleading.
