Note. 112 subjects, who underwent annual assessments upwards of 10 years since first depression evaluation (average 6.2 ± 3.0 assessments). Analyses included logistic generalized linear mixed models (GLMM) with random intercept and time. F test df = 516 or 515 for main predictors and interactions, df = 110 for linear time. The dependent variable is the presence vs. absence of suicidal ideation at any follow-up point in the 10 year span. Odds Ratios of individual terms included in interactions are not included.
