Model 1: unadjusted model; Model 2: adjusted for age and sex; Model 3: adjusted for Model 2 + systolic blood pressure, smoking status, alcohol intake, education levels, income levels, history of hypertension or diabetes, and physical activity; and Model 4: adjusted for Model 3 + estimated glomerular filtration rate, proteinuria, total cholesterol, and C‐reactive protein. BMI, body mass index; CI, confidence interval; HR, hazard ratio; MF ratio, muscle‐to‐fat ratio.
