Table 2 Unadjusted mean intake values at baseline, first and second follow-up and the results of the multilevel regression analyses showing the effect of the intervention at first and second follow up

From: Mothers' involvement in a school-based fruit and vegetable promotion intervention is associated with increased fruit and vegetable intakes – The Pro Children study
