The odds ratio for the prediction of an episode of major depression (MD) as predicted by the occurrence of a dependent stressful life event (dSLE) or a prior depressive episode (PDE) in the full twin sample, in monozygotic twins discordant for the risk factor exposure (Disc MZ), in dizygotic twins discordant for the risk factor exposure (Disc DZ), and in simulated case-control pairs matched on propensity scores (Prop score). These results are presented separately in male and female twins.
