Table 4 Multivariable linear regression analysis of the factors that correlated with cfPWV values among 120 hemodialysis patients

From: Serum osteoprotegerin is an independent marker of central arterial stiffness as assessed using carotid–femoral pulse wave velocity in hemodialysis patients: a cross sectional study

  1. Adopted factors: age, sex, diabetes, systolic blood pressure, corrected serum calcium, phosphorus, intact parathyroid hormone, glucose, C-reactive protein, and osteoprotegerin levels
  2. Adjusted R2 = 0.160
  3. cfPWV carotid–femoral pulse wave velocity, OPG osteoprotegerin, PTH parathyroid hormone
  4. p for trend
  5. *p < 0.05 is considered as statistically significant
