Kaplan-Meier survival curves of the evaluation and validation cohorts categorized into low- and high-risk groups. A significant association between the risk score and MACEs was observed in the evaluation cohort (a) and confirmed in the validation cohort (b). Survival curves between the higher apelin-12 group (>0.76 ng/mL) and lower apelin-12 group (≤0.76 ng/mL) in the evaluation cohort (c) and the validation cohort (d).
