  1. a Observed means for the intervention group were based on n = 51, 51, and 50 cases for self-report measures, biomarkers, and actigraphy variables, respectively, at month 3 and n = 50, 50, and 47 at month 6. For the control group, n = 47, 47, and 46 at month 3 and n = 46–47, 47, and 47 at month 6. The supplemental analysis reported in the text that included baseline as a time point was based on all 99 cases having any actigraphy data at any time
  2. b Estimated marginal means and statistical tests were obtained from a linear mixed model analysis, adjusted for baseline values of the outcome and specifying an unstructured variance/covariance matrix
  3. c Valid time needed to assess physical activity by ActiGraph was a minimum of 8 h of wear time or at least 2 valid days were required for calculation of composites at each time point. The mean (± SD) days worn ranged from 5.9 (±1.4) to 6.3 (±1.2) days. Group mean hours worn ranged from 15.2 (±2.6) to 16.2 (±3.2)
