NB. Diagnostic categories are not mutually exclusive/hierarchical.
NB. ‘No mental disorder’ cohort is a matched cohort (matched 10:1 for age and sex with the any mental disorder cohort; index date matches first diagnosis).
NB. ‘Any mental disorder’ includes all ICD-10 code F diagnoses (i.e., mental and behavioural disorders) and is not limited to the specific disorder groups presented.
NB. Total sample sizes were as following: 1,119,583 (51.2% male) individuals included in victimisation analysis, 1,131,106 (51.3% male) individuals included in perpetration analysis, and 1,119,462 (51.2% male) individuals included in the analysis of either outcome.
