* Values are means (95% Confidence Interval).
† Estimated mean change adjusted for initial value, gender, school random effect and significant interactions.
‡Difference between initial and final is significant at p < 0.05 in paired T-Test.
§ Change is different from the control group at p < 0.05 in ANOVA
** Estimated change from group with 1 dose of RTEC + Nutrition education guide is different to all other groups, at p < 0.05 in Adjusted ANOVA
†† Estimated change from group with 1 dose of RTEC + Nutrition education guide is different to group with 1 dose of RTEC and to control group, at p < 0.05 in Adjusted ANOVA
