  1. Model 1 adjusted for age and age2; Model 2 adjusted for age, age2, gender and migrant background; Model 3 adjusted for age, age2, gender, migrant background and mediators: parental education, and PLI at ages 6–8, 9–11 and 12–14; Model 4 adjusted for age, age2, gender, migrant background, mediators and interaction between PLI and migrant background. OR = odds ratio, 95% CI = 95% confidence intervals. N = number of observations, number of individuals in parenthesis. Obs. per individual: min. = 1, avg. = 5.0, max = 10
