Visualizing Pretest and Posttest Probabilities and Clinical Decision Thresholds in Diagnostic Algorithms Using the PPP command in Stata

2026-05-21

Abstract excerpt

<title>Abstract</title> <p> Background Updating and communicating the probability of disease following diagnostic testing are essential in evidence-based clinical decision-making. Methods We introduce <italic>ppp</italic> , a Stata command that creates a nomogram-style plot showing how a pre-test probability evolves into post-test probabilities across one or more steps in a diagnostic algorithm. The command...
