  1. Steps expressed as mean (SD) and MPA as geometric mean (geometric interval): geometric mean is antilog(m) and geometric interval is (antilog(m-SD), antilog(m + SD)), m and SD being the mean and the SD of the log-transformed MPA, respectively. MPA moderate intense physical activity (daily time spent in activities with an intensity of at least 3 METs). The rehabilitation effect at each time point is the difference (and its 95% confidence interval) between changes from baseline in the rehabilitation group and in the control group. As computation was made on log-transformed MPA, rehabilitation effect is expressed as a ratio (1.3 means + 30% in favor of rehabilitation). The p-Value on the baseline line assesses differences in baseline values, the other ones assess the effect of rehabilitation at each time point
