Question

Quizplus · Accepted Answer

Self-selection bias is not a common bias in meta-analyses and systematic reviews. The other biases listed (attrition bias, selective reporting bias, and publication bias) are all well-known sources of bias in these types of studies. Self-selection bias occurs when study participants are allowed to choose whether or not they want to participate in the study, which can lead to a non-representative sample. However, this type of bias is more commonly associated with individual studies rather than meta-analyses or systematic reviews.
