  • Clinical characteristics of the ICU patients with and without AKI at the time of enrollment. The serum creatinine concentrations at enrollment (and AKIN scores) were statistically different between the two groups. The other factors did not manifest statistical significance (overlapping 95% confidence intervals). ICU, intensive care unit; APACHE II, Acute Physiology and Chronic Health Evaluation II score; AKIN, Modified AKIN score based on serum creatinine measurements (ref 32). Continuous variables are given as means ± 1 SD.
