Of apples and oranges, file drawers and garbage: Why validity issues in meta-analysis will not go away
Abstract
This paper examines how threats to the validity of meta-analysis have been dealt with by clinical researchers employing this approach to literature review. Three validity threats were identified--mixing of dissimilar studies, publication bias, and inclusion of poor quality studies. Approaches to addressing these threats were evaluated for their effectiveness and popularity by surveying 32 published meta-analyses in clinical psychology. Distrust of meta-analysis, however, was found to transcend these validity threats. Other explanations for why this popular research strategy continues to receive widespread criticism were considered. Suggestions were made for how meta-analysis might better address these concerns.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
