Changes in overall physical activity for 4 valid days of wearing accelerometer at 12- month follow-up between participants randomised to usual practice (control) or to structured education (intervention)

*Adjusted for stratification factors: sex and ethnicity; change from baseline in accelerometer wear time and baseline value of outcome.
†Participants with missing outcome data or missing variables required for the model adjustment were excluded.
‡Missing data imputed using multiple imputation.
§Participants who did not engage with at least one group session of the programme have been excluded from the intervention arm.
