From: Effect of oral sodium bicarbonate on fibroblast growth factor-23 in patients with chronic kidney disease: a pilot study

  Regression Coefficient p-value
Serum Bicarbonate (mEq/L) -0.032 0.21
25-OH vitamin D (ng/mL) -0.005 0.45
1, 25-OH vitamin D (pg/mL) -0.012 0.005
Serum calcium (mg/dL) 0.032 0.83
Serum phosphate (mg/dL) 0.282 0.001
Urine calcium (mg/mg Cr) 2.911 0.34
