Changes in insulin sensitivity indexes at baseline, after seven months and ten months. PI(0−7) and PI(7−10) are P values for interaction between treatment allocation and time of visit in the repeated measures ANOVA model, for the pairwise comparisons between 0 and seven months and seven and ten months respectively, corrected for multiple testing by Bonferroni method. PI overall is P for interaction between treatment allocation and time of visit in the whole ANOVA model.
