* Values are means (95% CI) in mg/dL.

† Estimated mean change adjusted for initial value, gender, school random effect and significant interactions.

‡ Difference between initial and final significant at p < 0.05 in paired T-test.

§ Change in group with 1 dose of RTEC + Nutrition education guide is different to change in group with 1 dose of RTEC and to the control group at p < 0.01 in ANOVA.
