*indicates significantly different from PLA at the corresponding time point. The p-value is derived from an ANOVA and representative of a main effect for group by time. † indicates significantly different from PLA at week 0 as determined by independent T-tests of the delta values. Significant within-group time differences are indicated by ^a(different from pre), ^b(different from week 4), ^c(different from week 8), and ^d(different from week 10) for variables with a significant group x time interaction
