Note. Odds ratios (OR) less than 1.0 indicate a negative association between the predictor and bipolar spectrum disorder onset. CI = Confidence Interval; Age = Age at baseline; Fam Hx = Family History of bipolar disorder; ASRM = Altman Self-Rating Mania Scale scores; BDI = Beck Depression Inventory scores; M-SRM Regularity = Modified Social Rhythm Metric Regularity score.
