Resting Full-Cycle Ratio versus Fractional Flow Reserve: A SWEDEHEART-Registry-Based Comparison of Two Physiological Indexes for Assessing Coronary Stenosis Severity

Figure 3

ROC curves with accompanying table showing the diagnostic accuracy of RFR for detecting FFR <0.80. (a–d) ROC curves for all vessels, LAD, RCA, and LCX, respectively. AUC, area under the curve; CI, confidence interval; FFR, fractional flow reserve; LAD, left anterior descending artery; LCX, left circumflex artery; RCA, right coronary artery; RFR, resting full-cycle ratio; ROC, receiver operating characteristic; SE, standard error; Sn, sensitivity; Sp, specificity.
