  1. ∆ change, LM lean mass, PA physical activity, SD standard deviation, Traj trajectory, V visit
  2. aMean change (SD); P-val (ΔV3-V1), P-values for change in measure from baseline to visit 3 testing if change is significantly different than 0 within each joint-trajectory.
  3. bMeans reflect men who had non missing values at both, baseline and visit 3 for each measure.
  4. cSignificance observed in respective body composition trajectories within PASE trajectory; ANOVA
  5. dSignificance observed in respective body composition trajectories across PASE trajectory; ANOVA
  6. Tests of statistical significance, P = 0.05
  7. Total Men with visit 1 and visit 3 non missing measures: Body weight = 3894, Lean Mass = 3641, Fat Mass = 3641
