Figure 4.

Multivariable model for AKI-RRT and RRT/death. This figure shows (left panel) the odds of AKI-RRT and (right panel) the composite of AKI-RRT or death (RRT/death) within 14 days following ICU admission according to patient- and hospital-level characteristics. A total of 637 of 3099 patients (20.6%) developed AKI-RRT. A total of 1205 of 3099 patients (38.9%) developed RRT/death, of whom 413 (34.3%) developed AKI-RRT and did not die, 568 (47.1%) died without AKI-RRT, and 224 (18.6%) both developed AKI-RRT and died. Unless otherwise indicated, severity of illness covariates were selected as the worst value on ICU day 1 or 2. SOFA, Sequential Organ Failure Assessment.
