Number in the table is partial Pearson’s correlation coefficient (r) with adjustment of age and sex
ΔMAP, ΔFBS, ΔTC, ΔTG, ΔHDL-C, and ΔBMI are calculated by subtracting the values at follow-ups by the corresponding values at baseline
TG was log-transformed to approximate the normal distribution. Variables (TC, ΔHDL-C, and ΔFBS) not associated with any stiffness parameter were not shown
* = p < 0.10, ** = p < 0.01
