متن کاملSmall-study effects and time trends in diagnostic test accuracy meta-analyses: a meta-epidemiological study
BACKGROUND Small-study effects and time trends have been identified in meta-analyses of randomized trials. We evaluated whether these effects are also present in meta-analyses of diagnostic test accuracy studies. METHODS A systematic search identified test accuracy meta-analyses published between May and September 2012. In each meta-analysis, the strength of the associations between estimated...
متن کاملAsymmetric funnel plots and publication bias in meta-analyses of diagnostic accuracy.
BACKGROUND Despite the great possibility of publication bias in studies of diagnostic test research, empirical studies about publication bias have mainly focused on studies of treatment effect. METHODS A sample of 28 meta-analyses of diagnostic accuracy was selected from the Database of Abstracts of Reviews of Effectiveness (DARE). Methods used to deal with publication and related biases in t...
