  1. *p < 0.05
  2. a The linear mixed models included the factors of group and time, and the group × time interaction, with adjustment for age, sex, years of education, and type of medical insurance. Data are F statistics (numerator and denominator degrees of freedom)
  3. b Korean version of the Geriatric Depression Scale – Short Form; a higher score corresponds to more depressive symptoms (range: 0–15)
  4. c Participants were stratified by baseline SGDS-K scores (< 6 vs. ≥ 6)
  5. d Korean version of the Lubben Social Network Scale; a higher score corresponds to a stronger social network (range: 0–50)
  6. e Seoul Instrumental Activities of Daily Living; a higher score corresponds to worse daily function (range: 0–45)
  7. f Mini-Mental State Examination; part of the neuropsychological battery of the Consortium to Establish a Registry for Alzheimer’s Disease; a higher score corresponds to better global cognitive function (range: 0–30)
