Changes in body composition and performance in PRE-SUPP vs. POST-SUPP groups, and qualitative inferences about the effects on body composition and bench press strength.

Values reported as mean ± standard deviation (SD); BW body weight, FFM fat-free mass, FM fat mass. ^a ± 90% CI: add and subtract this number to the mean difference to obtain the 90% confidence intervals for the true difference. Qualitative inference represents the likelihood that the true value will have the observed magnitude.
