Means ± Standard Deviations. p values show results of t-test comparing groups at baseline (column A), comparing change from first to second baseline measurements within each group (column B), change from mean of baselines to post-treatment evaluation (column C), and change from mean of baselines to three month follow-up (column D).

^*denotes significant difference at p < 0.05.
