  1. The data of cfPWV, HD duration, glucose, iPTH and OPG showed skewed distribution and were log-transformed before analysis
  2. Data were analyzed using Pearson’s correlation analysis
  3. cfPWV carotid–femoral pulse wave velocity, HD hemodialysis, BMI body mass index, SBP systolic blood pressure, DBP diastolic blood pressure, BUN blood urea nitrogen, iPTH intact parathyroid hormone, CRP C-reactive protein, OPG osteoprotegerin, Kt/V fractional clearance index for urea
  4. *p < 0.05 is considered as statistically significant
