Subgroup analysis based on changes of VO_2peak pre- to post- training

(A) changes in VO_2peak, each individual is coded with one color.

(B) VO_2peak profile pre-to post-training by subgroup. Subgroup analysis of early phase DI (C), late phase DI (D), fasting serum glucose (E), HbA1C (F), fasting serum insulin (G), fasting serum c-peptide (H), fasting serum pro-insulin (I), proinsulin to C-peptide ratio (J). two-way ANOVA was used for sub-group analysis. ##p < 0.01 for interaction effect, ∗p < 0.05 and ∗∗∗p < 0.001 for differences pre-training and post-training.
