  • a Mean of 3-day diet records.

  • b Mean of 12 days of diet records collected at 3-, 6-, 9-, and 12-month follow-up visits.

  • c P calculated for intervention versus control group for the change in servings per day (average over follow-up minus baseline) for each variable with sex and baseline levels of the variable in the model.
