IL6 and acute kidney injury: In a logistic regression model, significant predictors of AKI in unadjusted analysis, were age >70 years (OR 2.58, 95% CI 1.17–5.65, p=0.018), pre-existing CKD (OR 4.21, 95% CI 1.82–9.76, p=0.001), higher IL-6 (OR 1.65, 95% CI 1.19–2.30, p=0.002), higher BNP levels (OR 2.31, 95% CI 1.05–5.04, p=0.036) and higher NET (OR 3.79, 95% CI 1.87–8.58, p=0.001).
