  1. *indicates significantly different from PLA at the corresponding time point. ‡ indicates significantly different from PLA at week 8. 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) and b(different from week 8) for variables with a significant group x time interaction
