Two hundred and thirty-seven (43.49%) of the individuals from the OCD cohort who died by suicide did not have any other recorded psychiatric comorbidity. Conversely, only 4.14% (n=178) of the OCD cases who had attempted suicide did not have any other registered psychiatric diagnosis. The percentage of recorded comorbidities in those individuals who died by suicide or attempted suicide in the OCD cohort is graphically shown in Figure 1. The risk of dying by suicide for those OCD cases without any recorded comorbidities (n=10 154) was similar to that for the full cohort (OR=13.18 (95% CI, 10.76–16.16)), but their risk for attempted suicide was significantly lower (OR=1.59 (95% CI, 1.36–1.87)).
