What is publication bias?

Researchers are more likely to publish a paper when that paper yields a relatively large treatment effect, and less likely to do so when the study yields a relatively small treatment effect. This can lead to a situation where the body of published studies is biased, in that it tends to exaggerate the true magnitude of the treatment effect. These issues are discussed in the book "Publication Bias in Meta-Analysis."
