disorder (MRR, 4.73 [95% CI, 2.91–7.20] for natural causes of death; MRR, 15.29 [95% CI, 7.34–27.61] for unnatural causes of death), and persons with OCD and both comorbidities (MRR, 2.51 [95% CI, 1.45–4.01] for natural causes of death; MRR, 29.38 [95% CI, 17.51–45.74] for unnatural causes of death) also had higher MRRs for natural and unnatural causes of death than those persons with only OCD (MRR, 1.66 [95% CI, 0.99–2.58] for natural causes of death; MRR, 2.61 [95% CI, 1.35–4.47] for unnatural causes of death). The additional exclusion of common comorbidities such as schizophrenia, attention-deficit/hyperactivity disorder, or conduct disorder still resulted in an increased MRR among persons with only OCD (1.71 [95% CI, 1.10–2.51]) (Figure).
