Fig. 1.

Allometrically scaled brachial FMD (A) and resting brachial diameter (B) at baseline and 6 and 12 wk in MICT, SIT, and CTL groups. Group means and SDs are presented on the left, whereas individual data are shown on the right. Scaled FMD group means and SDs were back-transformed from linear mixed-model estimated means and SEs, respectively. Individual scaled FMD data were estimated using unstandardized β from linear regression analyses. Group × time interaction for scaled brachial %FMD (P = 0.04): *P < 0.05 vs. MICT baseline; †P < 0.05 vs. SIT and CTL at same time. Main effect of time for resting brachial diameter (P = 0.03, two-way ANOVA): *P < 0.05 vs. MICT baseline (follow-up analysis with one-way ANOVA).
