All values are reported as means ±SD. Tx = treatment, VR-12 = The Veterans Rand 12, MCS = mental component score, PCS = physical component score, g = grams, d = day. *Denotes p-value < .05, for group by time interaction from mixed model ANOVA using all time points up to the time point denoted. For effect size using partial eta squared (ηp2), Sdenotes small effect size > .01, Mdenotes medium effect size > .06, Ldenotes large effects size > .14, for a significant or trending toward significant (p < .10) group by time interaction from mixed model ANOVA using all time points up to the time point denoted.
