The cumulative incidence lists the percentage of people with the examined disorder who died by suicide while accounting for competing risks by deaths due to other causes. The comparison group consisted of persons matched on sex, birth year, being alive and nonexposed in the calendar year of first diagnosis using a 2:1 matching ratio. A 30-year follow-up period was used for this analysis to ensure stability of the estimates.
Guillain-Barré, other brain disorders, and Alzheimer disease were only defined in International Statistical Classification of Diseases and Related Health Problems, Tenth Revision . These analyses were therefore restricted to a 23-year follow-up.
