Commercial app use linked with sustained physical activity in two Canadian provinces: a 12-month quasi-experimental study

Table 3 Changes in mean daily step counts between baseline and the last two recorded weeks stratified by engagement group and physical activity status within engagement group, least-square means (LSM) and 95% confidence intervals

Note: LSM have been averaged over the levels of gender and province and assumed an average level for all of the other continuous demographic variables included in the model. Cohen’s f² ≥ 0.02, f² ≥ 0.15, and f² ≥ 0.35 represents small, medium, and large effect sizes, respectively
^aThe difference between baseline and the average of last two recorded weeks were statistically significant at P < .0001 for all sub-group analyses
