CRP and acute kidney injury: Independent predictors were female sex (AOR 2.72, 95% CI 1.15–6.49, p = 0.02), consolidation in chest X-ray (AOR 3.38, 95% CI 1.13–10.1, p = 0.02), high C-reactive protein (CRP > 5 mg/dl, AOR 2.76, 95% CI 1.12–6.75, p = 0.03) and acute kidney injury (AOR 3.98, 95% CI 1.57–10.2, p < 0.01).
