Abstract:
|
Meta-analysis is the statistical synthesis of results of several studies that address a set of related research hypotheses. The synthesis will be meaningful only if the studies have been obtained systematically. However, publication bias is an issue for meta-analysis. Studies with significant results are more likely to be published than those with non-significant results, and published studies are more likely to be included in a meta-analysis than unpublished studies. In this presentation I will address publication bias in meta-analysis for observational studies using various statistical methods including the funnel plot, Rosenthal's Fail-safe, Orwin's Fail-safe N, Duval and Tweedie's Trim and Fill, and the cumulative meta-analysis.
