t: Year (0–15) after graduation. Cohort adjustment include year of compulsory school graduation (11 levels) and year of observation (16 levels) as fixed-effects. Demographic adjustment include cohort covariates, sex, and immigrant status. Mediation covariates varied by outcome as follows: Income included days unemployed, presence of study benefits and disability pension respectively. Unemployment included disability pension and presence of study benefits. Disability pension included an indicator of being at least 19 years of age in 2003 or later due to an eligibility requirement implemented this year. Comorbidity includes indicators for a lifetime diagnosis of developmental disorder or intellectual disability. Lifetime EA includes indicators of lifetime secondary and tertiary educational attainment.
