Linear Mixed Effects model analysis with unstructured covariance was used to assess the efficacy of intervention on each outcome variable. Test of time by group interaction used to test the efficacy of intervention (see p value for overall interaction). Results are mean (SE). Significant p values (p <0.05) are indicated in bold. Effect size (ES) is calculated as (2 × t value)/√DF, where degrees of freedom (DF). Hand calculations for between- and within-group differences may not be equal to data shown because all data were rounded to 0.1 decimal place. Weight changes from scale weight (kg) do not match weight changes from sum of DXA fat mass and lean mass due to the different methodologies used to measure these outcomes. For CR: n=12 for baseline and week 8; n=10 for week 32; For ADF: n=13 for baseline and week 8; n=11 for week 32; Non-missing observations: n = 71.
