Receiver operation characteristic curves of post-procedural Murray law-based quantitative flow ratio (μQFR) measurements and diameter stenosis for the prediction of vessel-oriented composite endpoint (VOCE). Receiver operator characteristic curves for the VOCE; A. Post-procedure diameter stenosis (AUC 0.61, 95% CI 0.53–0.68; p = 0.18); B. Post-procedural μQFR (AUC 0.74, 95% CI 0.67–0.80; p < 0.001); C. Post-procedural μQFR improvement (AUC 0.67, 95% CI 0.60–0.74, p = 0.001); AUC — area under curve; CI — confidence interval.
