  1. Associations between each BDI factor and BNSQ insomnia score were tested in each reproductive group separately via generalized linear models. Potential outliers included in the models.
  2. Significant items are in italic.
  3. Note: BDI = Beck depression inventory; BNSQ = basic Nordic sleep questionnaire; 95% CI = 95% confidence intervals.
