Kaplan–Meier analysis for prediction of major adverse cardiovascular events stratified by the presence of elevated triglyceride glucose index and diabetes mellitus The Kaplan–Meier curves demonstrate significant differences among the three groups in the cumulative event rates of MACE. The highest event rates are observed in Group C, (patients with DM; log-rank test, p < 0.001), followed by Group B (patients without DM with an elevated TyG index; log-rank test, p = 0.047) and Group A (patients without DM without an elevated TyG index). MACE, major adverse cardiovascular events; TyG, triglyceride glucose.
