Select the one correct one answer.  A parallel-group randomized controlled trial evaluated the effect of a school-based, nurse-led healthy weight management afterschool program on children’s weight, a key predictor of adult cardiovascular health. Following baseline measurements, 132 child-parent dyads were randomized to intervention (A; 9-month healthy weight management program) or control (B; 9-month social-emotional learning program) conditions.

Only the statistician had access to this schedule, and all study staff members and research participants remained blinded to the allocation sequence.
