Receiving operating characteristics curves for MACE from Cox proportional hazards models with and without spermidine in patients with AMI (n = 377). In the model with spermidine, the optimal cut-off value for PI was 0.502 at Youden’s index of 0.387, shown in red. In the model without spermidine, the optimal cut-off value for PI was 0.545 at Youden’s index of 0.357, shown in yellow. Comparison between the AUCs is noted in the bottom panel. MACE: major adverse cardiac events, AMI: acute myocardial infarction, PI: prognosis index, AUC: areas under the curves.
