From: Neutrophil gelatinase-associated lipocalin as a biomarker for predicting acute kidney injury after coronary artery bypass grafting

Parameter Mean ± SD Correlation coefficient (r)** p value
Creatinine level at 6 h 0.94 ± 0.05 − 0.109 0.82
Creatinine level at 12 h 1 ± 0.06 − 0.045 0.92
Creatinine level at 24 h 1.09 ± 0.07 0.33 0.47
Creatinine level at 48 h 1.53 ± 0.09 0.857 0.014*
  1. *p value less than 0.05 is considered statistically significant p value < 0.001 is highly significant
  2. **Pearson’s rank correlation coefficient
