  1. For the physical parameters, physical performance, cognitive function, and brain atrophy, the p-value for male vs. female was calculated using an unpaired t-test
  2. For the comorbidities, the p-value for male vs. female was calculated using a chi-squared test
  3. BMI body mass index, GDS Geriatric Depression Scale, SD standard deviation, CS chair stand, OLS one leg standing with open eyes, GS gait speed, TMT Trail Making Test, WMS-R LM Wechsler Memory Scale-Revised Logical Memory Immediate, GM gray matter
  4. aLower scores indicate better performance
