the outcome, our findings might not be representative of the entire spectrum of OCD but of only those persons with more severe OCD. Second, some of the causes of death may be prone to misclassification. It is possible that some accidental deaths, in fact, were suicides, whereas most deaths classified as suicides reflect true suicides. This potential misclassification might lead to an underestimation of the cases of suicide in our cohort and thereby might have resulted in an underestimation of the observed MRRs for suicide.
