^*The reference group was the general population of Sweden. We defined a 3-year washout period (1987–1989) to increase the number of people who had newly diagnosed schizophrenia and minimise potential confounding due to the high mortality associated with long-term hospitalisation

ARR, admission rate ratio; CI, confidence interval; N, number of admissions.
