S.: serum, Ca: calcium, Ph: phosphorus, CRP: C-reactive protein, ADMA: asymmetric dimethylarginine, METs: metabolic equivalents, WSR: Wilcoxon signed rank test, χ2: chi-square test, significant ( ); highly significant ( ). Continuous data are expressed as mean ± standard deviation (if parametric) or median (interquartile range) (if nonparametric). |
