Long-term (30-to 40-year) follow-up data for 76 manic patients, 182 depressives. 170 schizophrenics, and 109 controls showed that 10 per cent of the schizophrenics, 8.5 percent of the manics, and 10.6 percent of the depressives who were decreased had died by suicide. None of the controls had committed suicide. The authors suggest that suicide is a significant outcome factor in all three of these illnesses and is likely to occur at an earlier age in schizophrenia than in the other illnesses.
对76名躁狂症患者、182名抑郁症患者、170名精神分裂症患者和109名对照者进行的长期（30至40年）随访数据显示，病情有所缓解的精神分裂症患者中有10%、躁狂症患者中有8.5%、抑郁症患者中有10.6%自杀身亡。对照者中无人自杀。作者认为，自杀是这三种疾病的一个重要结局因素，而且精神分裂症患者自杀的年龄可能比其他疾病患者更早。
