Exclusion of patients with missing data for creatinine, urea, MAP, pH; patients included n = 1794. The area under the receiver operator characteristic curve was 0.784 (Hosmer-Lemeshow chi-squares = 7.769; two degrees of freedom, P = 0.456).
AKI = acute kidney injury; CI = confidence interval; CVS = cardiovascular; GI = gastrointestinal; HAEM = haematological; HEP = hepatic; ICU = intensive care unit; NEURO = neurological; OR = odds ratio; RESP = respiratory; RRT = renal replacement therapy; SE = standard error.
