  1. Abbreviation: RIFLE, risk of renal failure, injury to kidney, failure of kidney function, loss of kidney function and end-stage renal failure; AKIN, acute kidney injury network; KDIGO, kidney disease improving global outcomes; df, degree of freedom; AUROC, areas under the receiver operating characteristic curve; SE, standard error; CI, confidence intervals
  2. Values in bold are statistically significant (P-value < 0.05).
