  1. The values represent the proportion of variance (R2) in the regression model
  2. In model 1, the linear regression analysis was performed only on age, gender, and education
  3. In model 2, the linear regression analysis was performed on all the sociodemographic, lifestyle, and medical variables
  4. Both models used the enter method
  5. AVLT-IR Auditory Verbal Learning Test—immediate recall, AVLT-LR Auditory Verbal Learning Test—long recall, AVLT-SR Auditory Verbal Learning Test—short recall, DSB digit span backwards, DSF digit span forwards, MMSE Mini-Mental State Examination, MoCA Montreal Cognitive Assessment, SCWT-IT Stroop Color-Word Test Interference Trial, SDMT Symbol Digit Modalities Test, TMT Trail Making Test, LMT-IR Logical Memory Test—immediate recall
