Quizplus · Accepted Answer

Meta-analyses face challenges such as publication bias, which occurs when studies with favorable results are more likely to be published while studies with negative or inconclusive results are not. This can skew the overall results of the meta-analysis. Additionally, there may be a "file drawer" problem where studies with negative or inconclusive results are not even submitted for publication, further biasing the results. Finally, the meta-analysis is only as strong as the studies on which it is based, so weaknesses in individual studies can weaken the overall meta-analysis.
