  1. Associations between each BDI factor and REM sleep variables were tested in each reproductive group separately via generalized linear models. Potential outliers included in the models.
  2. Significant items are in italic.
  3. ^not age-adjusted.
  4. Note: BDI = Beck depression inventory; 95% CI = 95% confidence intervals; REM = rapid eye movement.
