ALB and diabetes mellitus: For MACE in Figure 3A, the association was statistically significant in patients with hypertension (hazard ratio, 2.026, 95% confidence interval [CI], 1.626 to 2.526), those aged ≥65 years (hazard ratio, 1.995, 95% CI, 1.704 to 2.337), patients with GFR < 45 mL/min/1.73 m2 (hazard ratio, 1.227, 95% CI, 1.021 to 1.474), those with diabetes mellitus (hazard ratio, 1.467, 95% CI, 1.281 to 1.680), and those with low serum albumin (hazard ratio, 1.404, 95% CI, 1.179 to 1.672).
