There were 313 suicides in the cohort between 1976 and 2011. Among 26 020 respondents with known smoking status in 1975, there were 232 suicides (see Table 1). Forensic autopsy was conducted in 25% of all deaths in the cohort and in 98% (228/232) of suicide deaths. The overall mortality of the twin cohort members did not differ from that of the Finnish population (Kaprio, 2013).
