*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. 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
