  1. K-MMSE Korean version of the Mini-Mental State Examination
  2. Values in the Table are mean (SD), median (IQR), or number (%)
  3. P for trends for body mass index (p = 0.013) and K-MMSE (p < 0.001) were statistically significant. p for trends for age (p = 0.576) and sex (p = 0.052) were not significant. We excluded participants who were assigned to scale 9 (terminally ill) on the Clinical Frailty Scale-Korean
