Receiver operating characteristic (ROC) for postoperative complications to set the cut-off values of CAVI and AAC score. a The ROC curve indicated that an optimal cut-off value of 10 for CAVI had a sensitivity and specificity of 71.4% and 71.8%, respectively. The area under the ROC curve for CAVI was 0.727 (95% CI, 0.592–0.861). b The ROC curve revealed that an optimal cut-off value of 10 for the AAC score had a sensitivity and specificity of 57.1% and 75.5%, respectively. The area under the ROC curve for the AAC score was 0.691 (95% CI, 0.539–0.8441)
