Fig 2. Adherence to Fitbit and change in Actigraph measured moderate-to-vigorous physical activity using uniaxial cut points.
Change in Actigraph measured Moderate-to-Vigorous Physical Activity (MVPA) across the intervention period (week 2 to 12) and follow up period (week 12 to 24) as a function of percentage engagement with the Fitbit over the same period. R is Spearman’s rank order correlation.
