  1. Linear regression models were performed to assess the cognitive decline according to the circadian rest-activity pattern. Model 1, unadjusted analysis; model 2, adjusted for age, sex, T-tau/Aβ42 ratio, educational level, and season of the year
  2. Aβ42 amyloid-beta protein, CI confidence interval, T-tau total-tau
