Actigraphy-measured vector magnitude count is an estimate of physical activity intensity. The total vector magnitude counts per day was measured over 7 days using an actigraphy device, and the median value over the 7 days was obtained. This outcome measure is the change in the 7-day median value from baseline to follow-up, adjusted for the baseline value, sex, and actigraphy device wear time.
