Overconfident results with the bivariate random effects model for meta-analysis of diagnostic accuracy studies by Furuya-Kanamori, Luis

“…In 2001, Rutter and Gatsonis proposed the hierarchical summary receiver operating characteristic (HSROC) model,1 and in 2004 Macaskill described an empirical Bayes approach.2 Soon after, in 2005, Reitsma et al. proposed the bivariate random effects model,3 which has been widely adopted and is the most commonly used method for diagnostic meta-analysis.4 However, as pointed out by Diaz,5 the statistical performance of the bivariate model has not been scrutinized. …”
