Association between cumulative fluid balance relative to baseline and risk-adjusted hospital mortality. AKI =occurrence of acute kidney injury; CFB =cumulative fluid balance expressed as quintiles; CKD =pre-existing chronic kidney disease; SMR =Standardized Mortality Ratio. SMR for each AKI/CKD subgroup by CFB quintiles was calculated as follows: SMR =observed/predicted mortality; where predicted mortality was determined by the multivariable logistic regression estimate for each AKI/CKD subgroup
