DBAS-16 global, subscale, and individual items scores are presented for comorbid depression and hypersomnolence (MDD+/HYP+), depression without hypersomnolence (MDD+/HYP−), and healthy controls (HC). Values are provided as means ± standard deviation. F- Statistic and corresponding p value are documented for the main effect of group. Bonferroni corrected p values are provided for pairwise comparisons, when applicable. A hyphen (−) denotes a nonsignificant result. N/A indicates that pairwise comparisons were not performed due to a nonsignificant group effect.
