Percentages are given as total within group; continuous data are presented as mean ± standard deviation; HPG, high-pressure group; LPG, low-pressure group; CI, confidence interval; AKI, acute kidney injury; Hct, hematocrit; sCr, serum creatinine; eGFR, estimated glomerular filtration rate; ICU, intensive care unit.
