Reference categories: male student; mother low education, 18–19 years of age, low/no school absence.
Interclass correlation coefficient (ICC), estimates of fixed effects, 95% CI in parentheses and p values (**significant 0.01, *significant 0.05).
Bold values are statistically significant (p<0.05).
SP, sickness presence.
