Fig. 1. Cox proportional hazards regression modelling of factors associated with mortality in a Swedish national population-based sample of schizophrenia (SCZ) cases.

The unadjusted model considers each factor individually and the adjusted model includes all listed factors in one model. The adjusted model additionally contains major depressive disorder. Total N for all exposures in the unadjusted model: 13,727 SCZ cases (1268 died), except for education years (13,375 SCZ cases, 1112 died) and SCZ family history score (13,275 SCZ cases, 1179 died). Total N for the adjusted model: 12,973 SCZ cases (1064 died). The information in this figure is the same as what is represented in Supplementary Table 3. NS not significant.
