^aSuper compliers are defined as participants in the Polyp Prevention Trial intervention who completed all 4 annual food frequency questionnaires and met a total of 9–12 food frequency questionnaire goals over the trial period; goal-achieving controls are controls selected as having a proportion of “dietary compliance” similar to that of the intervention group.
