  • Concordance probability indicates the discriminatory power and predictive ability of statistical models for respective outcomes. It estimates the probability of concordance between predicted and observed outcomes. MACE, major cardiovascular event—defined as a composite of fatal cardiovascular event, nonfatal myocardial infarction, nonfatal stroke, or incident peripheral vascular disease.

  • a Adjusted for age, sex, and body mass index.

  • b Model 1 plus eGFR and urinary albumin-creatinine ratio.

  • c Model 2 plus prevalent cardiovascular disease, diabetes and hypertension at baseline, systolic BP, diastolic BP, serum high and LDL concentration, serum C-reactive protein and phosphorus concentration, prescription of diuretics, and lipid- and BP-lowering medication.
