Small Study Effects in Diagnostic Imaging Accuracy: A Meta-Analysis.

ABSTRACT:

Importance

Small study effects are the phenomena that studies with smaller sample sizes tend to report larger and more favorable effect estimates than studies with larger sample sizes.

Objective

To evaluate the presence and extent of small study effects in diagnostic imaging accuracy meta-analyses.

Data sources

A search was conducted in the PubMed database for diagnostic imaging accuracy meta-analyses published between 2010 and 2019.

Study selection

Meta-analyses with 10 or more studies of medical imaging diagnostic accuracy, assessing a single imaging modality, and providing 2 × 2 contingency data were included. Studies that did not assess diagnostic accuracy of medical imaging techniques, compared 2 or more imaging modalities or different methods of 1 imaging
