Fig. 3

Identical pretest probabilities within target conditions. The figure shows the number of target conditions with two or more analyses and the use of identical pretest probabilities for all of the meta-analyses within a target condition. Black bars indicate the number of pretest probabilities that were outside the prevalence range of at least one meta-analysis for the target condition. White bars indicate the number of pretest probabilities that were inside the prevalence ranges of all individual meta-analyses for that specific target condition. The gray bar indicates that it was unclear whether these identical pretest probabilities were inside or outside the disease prevalence ranges. No bars were drawn in the figure when there were no identical pretest probabilities used for all of the meta-analyses within a target condition. DTA: Diagnostic Test Accuracy, TC: Target Condition
