Note: The sign of the coefficient indicates the direction of the relationship (direct for positive and inverse for negative coefficient), and the magnitude of the coefficient indicates the strength of the relationship. Confidence intervals not including 0 indicate a statistically significant correlation.

Abbreviations: BUN, blood urea nitrogen; CI, confidence interval; ERYS, red blood cells; K, potassium; Mg, magnesium; P, phosphorus; PCV, packed cell volume; SBP, systolic blood pressure (n = 53); sCREAT: serum creatinine; SDMA: symmetric dimethylarginine (n = 46).
