Time-dependent tree-structured survival analysis model. Each terminal node of the tree shows estimated time to 50% events and 25% events, along with 95% confidence intervals. For continuous variables, observations ≤ the cut point are sent to the left child node. For the categorical variable, observations with no first degree relatives with a mood disorder are sent to the left child node. Abbreviations: % MDE = % Weeks in a major depressive episode, % MIX = % Weeks with mixed mood symptoms, % SUD = % Weeks with a substance use disorder, % PST = % Hours spent in inpatient or outpatient psychosocial treatment, FDRs with Mood dx = First degree relatives with a history of mood disorders.
