Analyses using all available data at each follow-up.

PACE-UP study: N = 954 at 3 months, 956 at 12 months, and 681 at 3 years. PACE-Lift study: N = 280 at 3 months, 273 at 12 months, and 225 at 4 years.

All models include treatment group, practice, gender, age at randomisation, and month of baseline accelerometry as fixed effects and household as a random effect in a multilevel linear regression model. The results shown are the change in each intervention group relative to the change in their control group.

The effect estimates, 95% confidence intervals, and p-values were obtained from the model output.
