Survivors (n=95) Non-survivors (n=22) p-value
Ca++ (mg/dL) 4.7 [4.6-4.9] 4.4 [3.8-4.7] 0.001
GFR (mL/min/1.73 m2) 60 [48-60] 59 [26-60] 0.042
Phosphorus (mg/dL) 2.9 [2.3-4.2] 3.2 [2.7-4.3] 0.334
Magnesium (mg/dL) 2.0±0.4 1.9±0.36 0.345

GFR: glomerular filtration rate calculated by the Modification of Diet in Renal Disease Study Group (MDRD). Values are expressed as the total mean ± 95% confidence interval OR the median [interquartile range].
