![]() ![]() In order to run a meta-analysis of diagnostic odds ratios simply use the odds ratio meta-analysis function with the experimental group as the true (test correct) outcomes and the control group as the false outcomes – enter a as experimental group responders a+d as experimental group number b as control group responders and b+c as control group total. This function can also be applied to a review of diagnostic test studies to give an overall sensitivity or specificity as follows:Īnother way to summarise diagnostic test performance is via the diagnostic odds ratio:ĭiagnostic odds ratio = true/false = (a * d)/(b * c) This function enables you to calculate an overall proportion from a set of proportions, for example from a systematic review of studies of adherence with a particular drug treatment.
