Risk ratios adjusted for child sex, maternal ethnicity, maternal age at birth, multiple births for all cohorts. Also see online supplemental table S3. Sample sizes differ from baseline N reported in table 1 due to missing data for SES exposure in early childhood or ALCHC in late childhood or cohort attritio.
