Note: Mean values (SD) of average SSB intake in litres, number of servings, and prevalence of children taking SSB with them to school. Figures are given for baseline and follow-up, in intervention and control groups. Also shown is the intervention effect (B (95% CI) and OR (95% CI)) between both groups for the parent reports (n = 356), child reports (n = 387) and observation reports (n = 959). Significant effects are shown in bold. ^a = in favour of intervention group; ^b = difference (p < 0.05) between intervention and control group at baseline; ^c = regression coefficients and odds ratios of the unadjusted models (only adjusted for baseline intake and school-pair) and fully adjusted models (in addition to baseline intake and school-pair, also adjusted for grade, gender, ethnic background and weight status of the child and educational level of the caregiver).
