Suicide, a composite of deliberate self-harm or death by suicide, was ascertained based on hospitalizations and emergency department visits. Cause-specific hazard models were used to evaluate the association between stroke and suicide, and major depression was treated as a time-varying covariate. Cause-specific hazard models evaluated the association between sociodemographic factors and suicide in stroke survivors. The modifying effect of major depression was assessed by adding an interaction term between stroke and major depression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      We included 64,719 matched pairs of patients with stroke and general population controls (45.4% female, mean age 71.4\u2009years). In the 627,774 person-years follow-up, 436 cases and controls had an episode of self-harm or died by suicide, with 203 (67.4%) events in stroke survivors occurring after the first year. Compared to matched controls, stroke survivors had a higher rate of suicide (11.1 vs 3.2 per 10,000 person-years, hazard ratio (HR) 2.87; 2.35\u20133.51).
