Kaplan–Meier plots of patient survival for nondiabetic patients with and without metabolic syndrome (MES). Plots are defined by (A) World Health Organization criteria, (B) International Diabetes Federation criteria, (C) original National Cholesterol Education Program criteria, and (D) modified National Cholesterol Education Program criteria. Data are compared by log-rank test. When only nondiabetic patients are analyzed, there is no significant difference in patient survival between patients with and without MES, irrespective to the defining diagnostic criteria.
