  1. Abbreviations: MVPA, Moderate and/or vigorous physical activity; RPAQ, Recent Physical Activity Questionnaire.
  2. Results are measured in minutes/day presented as mean (SD). Treatment effects are mean differences (95% confidence intervals), adjusted for baseline activity; with dummy variables where baseline levels missing (2 accelerometer, 3 RPAQ).
