*Total N includes participants with complete data on alcohol consumption social class and qualification level (33 years).
†Z-scores are estimated from multilevel models of maths trajectories from 7–16 years. Scores are negatively coded: an increase in z-score represents a decrease in relative rank between 7 and 16 years. Change in z-scores is measured in standard deviations.
