N=69 695 for the full cohort; N=36 912 for the subcohort of individuals born in 1956 or later. Episodes of medical care for intentional self-harm received a primary diagnosis in the National Patient Register (NPR) of ICD-8: E950-E959, ICD-9: E950-E959, or ICD-10: X60-X84. Since individuals born before 1956 are left censored with follow-up beginning in 1969, we also present results from the subcohort of persons born in 1956 or later, all of whom were followed up from age 13 through 2010.
*Between age 13 and 2010 for individuals born after 1956.
†Model A: adjusted for age and country of birth.
‡Model B: with additional adjustment for educational attainment as of 2010 and household per capita income in 2010.
