Multivariable model 1: adjusted age, sex, estimated glomerular filtration rate, high-sensitivity C-reactive protein, lean body mass, alcohol intake, smoking status, income status, HOMA-IR, and exercise participation model 2: adjusted for model 1 plus resting heart rate model 3: adjusted for model 2 plus waist circumference.

DM: diabetes mellitus, RGS: relative grip strength, CI: confidence interval, HR: hazard ratio, BMI: body mass index, HOMA-IR: homeostatic model assessment for insulin resistance.

*Incidence density=case/person−year×1,000.
