From: Incidence and diagnosis of Acute kidney injury in hospitalized adult patients: a retrospective observational study in a tertiary teaching Hospital in Southeast China

Variable Failure to timely diagnose AKI
P value OR 95% CI
Chronic kidney disease (yes: no) <0.001 0.27 0.16–0.45
Presence of tumor (yes: no) 0.032 1.47 1.03–2.00
AKI Stage 2: stage 1 0.874 0.97 0.67–1.41
AKI Stage 3: stage 1 <0.001 0.24 0.17–0.36
Presence of oliguria (yes: no) 0.006 0.51 0.32–0.82
Receiving renal replacement therapy (yes: no) <0.001 0.06 0.02–0.14
Extra-Renal Organ Failure (yes: no) <0.001 0.63 0.53–0.76
Serum albumin (per 1 g/L) <0.001 1.04 1.11–1.06
Blood urea nitrogen (per 1 mmol/L) <0.0001 0.95 0.93–0.96
C statistic (95% CI) 0.88 (0.86–0.90)
Test of Goodness of Fit χ2 = 10.88, P = 0.208
  1. AKI acute kidney injury, Variables included in the multivariate logistic regression comes from variables that were found to be statistically significant (P < 0.05) in the univariate analysis (see in Additional file 1: Table S5)
