  1. OR Odds ratio, CI Confidence interval
  2. Model 1: adjusted for age, sex, and baseline frailty status (prefrailty vs. nonfrailty);
  3. Model 2: further adjusted for residence, marital status, education level, economic independence, smoking status, drinking status, regular exercise, sleep time, body mass index, dentition status, calf circumference, and season of blood draw;
  4. Model 3: further adjusted for albumin and high-sensitivity C-reactive protein;
  5. a25-Hydroxyvitamin D < 50 nmol/L; b 25-Hydroxyvitamin D ≥ 50 nmol/L
