  1. Abbreviations: PA, physical activity; OR, odds ratio; CI, confidence intervals.
  2. †Red/processed meat target: <5 servings of red and processed meat per week, including <2 servings of processed meat.
  3. Refined grain target: <2 servings of refined grain per day.
  4. PA general health target ≥30 minutes of moderate-to-vigorous intensity physical activity (MVPA) 5 days a week.
  5. PA cancer outcome target ≥60 minutes of MVPA 5 days a week.
  6. ‡The “overall” comparison was a test for the effect of the interventions at all follow-up time points (four levels at 6, 12, 18 and 24 months) using repeated measures mixed effects models, where the time point were regarded as a categorical variable.
