Fig. 1From: Serum osteoprotegerin is an independent marker of central arterial stiffness as assessed using carotid–femoral pulse wave velocity in hemodialysis patients: a cross sectional studyCorrelation between serum calcium levels and carotid–femoral pulse wave velocity (cfPWV) values based on the tertiles of serum osteoprotegerin levels. Data of cfPWV showed skewed distribution, and their correlation with corrected serum calcium levels was analyzed using Spearman’s correlation analysis. *p < 0.05 is considered as statistically significantBack to article page
