Table 2 Pearson’s correlation coefficient (r) between risk factors and progression rate of arterial stiffness

From: Determinants of arterial stiffness progression in a Han-Chinese population in Taiwan: a 4-year longitudinal follow-up

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