Depression severity over longitudinal follow-up differed between the migraine and non-migraine groups, but mania severity did not differ
Depression severity was assessed using the PHQ-9 and mania severity was assessed using the Altman Self-Rating Mania Scale (ASRM); Y-axis reflects group mean scores +/− standard deviation on these measures. Models comparing depression and mania severity accounted for age, BMI, sex, BPI vs. BPII.
