  1. Each of the regressions was performed separately for each independent variable (TMT-A, TMT-B, and digit symbol)
  2. Model 1: includes two hand variables analyzed separately as independent variables and adjusted for age (a continuous variable), sex, years of education, TMIG-Index of Competence, GDS, hypertension, stroke, heart disease, diabetes and MMSE
  3. Model 2: includes two hand variables analyzed together as independent variables and adjusted for the same covariates as Model 1
  4. CI Confidence Interval, HG Handgrip strength, PPT Purdue Pegboard Test
  5. aThe total number of subjects analyzed was 207
