Odds ratios for AKI.

Values are expressed as mean ± standard deviation in continuous variables and n/total (%) in categorical variables. Difference in univariate analysis was calculated by t-test in continuous variables and chi-square test in categorical variables. The reference of the continuous variables in multivariate analysis was every 1 unit increase of each variable. AKI, acute kidney injury; CV, cardiovascular; ECMO, extracorporeal membrane oxygenation; VA, venoarterial; VV, venovenous; IABP, intraarterial balloon pump; LOS, length of stay; PEEP, positive end expiratory pressure; PIP, peak inspiratory pressure; BUN, blood urea nitrogen; WBC, white blood cells; RDW, red cell distribution width; CRP, C-reactive protein; SAPS2, Simplified acute physiology score 2.aThe total numbers of AKI/non-AKI group of pump speed, PEEP, PIP, total bilirubin, albumin, CRP and initial SAPS2 were 264/57, 254/53, 253/53, 262/57, 263/57, 237/53 and 256/56, respectively.Odds ratios for AKI.
