  1. B Partial regression coefficient, SE Standard error, β Standardized partial regression coefficient, t t-ratio, 95% CI 95% confidence interval, R2 Coefficient of determination, eGFR Estimated glomerular filtration rate, IGF-1 Insulin-like growth factor-1, 25(OH)D 25-hydroxyvitamin D
  2. Multiple regression analysis was performed with grip strength and gait speed as dependent variables, and with age (years), height (cm), weight (kg), BMI (kg/m2), SOS, SMI, HbA1c, eGFR, 25(OH)D, and pentosidine as independent variables in men and women
  3. The selection of modeling was made using the stepwise method
