Receiver operating characteristic curve (ROC) analyses for biomarkers in relation to incident arrhythmia. ROC curves and the corresponding area under the curve (AUC) values were calculated after conducting univariate logistic regression modeling to predict incident arrhythmia for each biomarker, respectively. (A) hsTNT = high-sensitive troponin T; optimal cut-off value according to Youden index analysis: 27.5 pg/mL. (B) NTproBNP = n-terminal pro-B-type natriuretic peptide; cut-off value: 1518 ng/L. (C) CRP = C-reactive protein; cut-off value: 120.5 mg/l. (D) IL-6 = interleukin-6; cut-off value: 82.5 ng/L.
