Subgroup analyses. The effects of balanced crystalloids versus saline on day 2 urinary NGAL and KIM-1 concentrations are displayed for patients in each pre-specified subgroup. Scores on the Acute Physiology and Chronic Health Evaluation (APACHE) II range from 0 to 71, with higher scores indicating a greater severity of illness [23]. Acute kidney injury (AKI) of stage 2 or higher is defined according to the Kidney Disease: Improving Global Outcomes creatinine criteria [19]
