**Between group differences always compare to the intervention arm and are adjusted for baseline outcome value, IMD, school size, percentage of girls recruited, percentage of Y5 pupils recruited, LEA, and school-level clustering.
†After school period =3.30 to 8.30 pm.
††I = intervention; C = control.
