Abstract
Dear editor of the Canadian Journal of Psychiatry,
The figures we reported as incidence are actually annual prevalence.
The incidence figures are about 10 times lower in 2016. The incidence crude rates per 100,000 inhabitants with their 95% confidence intervals (CIs) and relative risks (RRs) were for males: 78 (73–84) in Montreal versus 53 (51–56) in the rest of Quebec, with an RR of 1.47; for females: 68 (62–73) in Montreal versus 43 (41–46) in the rest of Quebec, with an RR of 1.58; for both males and females: 73 (69–77) in Montreal versus 48 (46–50) in the rest of Quebec, with an RR of 1.52. The nonoverlapping 95% CI indicates a significantly 50% higher incidence in Montreal, and a statistically significant higher incidence in both males and females in Montreal compared to the rest of Quebec.
Both annual prevalence and incidence figures confirm a higher proportion of people with schizophrenia in large urban areas like Montreal and shall be taken into account in equitable resource allocation of specialist resources.
