In the multivariate stepwise logistic regression analysis adjusted for age and sex, ARDS and serum albumin on admission were independent predictors for stage 3 AKI (ARDS: odds ratio (OR) = 9.05 (95% CI = 1.05–78.14), p = 0.04; serum albumin: OR = 0.02 (95% CI = 0.001–0.87), p = 0.04). Here, ALB is linked to acute kidney injury.
