Examining the Association between Estimated Prevalence and Diagnostic Test Accuracy using Directed Acyclic Graphs
Yang Lu, Robert Platt, Nandini Dendukuri
There have been reports of correlation between estimates of prevalence and test accuracy across studies included in diagnostic meta-analyses. It has been hypothesized that this une…
