  1. Model 1: adjusted for age, gender, education, APOE4 status, vascular risk score, use of sleep pill, Hamilton Depression Rating Score. Model 2: adjusted for covariates of model 1 + global Aβ deposition. Global Aβ deposition was natural log-transformed to achieve normal distribution
  2. AD-ND Alzheimer’s disease signature region neurodegeneration, aOR adjusted odds ratio, CI confidence interval, beta-amyloid, APOE4 apolipoprotein E ε4
  3. aGood sleep quality was taken as a reference, so aOR represents the likelihood of being AD-ND positive for bad sleep quality compared with good one
