a
Analysis adjusting for baseline score, child age and gender as fixed effects and school and classroom as random effects. Intervention group = 1, control group = 0.
b
Effect size = regression coefficient/pooled standard deviation at baseline.
c
Sum of standardised scores of variables loading on each factor (see Table 3 for details).
d
Transformed scores (square) used in the analyses.
