  • The main analysis was based on the intention-to-treat population.

  • *P value: McNemar tests (changes in each group).

  • †P value: generalised linear models (differences in the changes from baseline to end of intervention of the intervention and control groups).

  • ‡Sugary drinks, accounting for three categories: commercial juice, sodas and cokes.
