*Models were fitted among 5,313 patients with complete data and were adjusted for age, sex, race, dose of norepinephrine equivalents, APACHE III score, and cumulative fluid balance. Hosmer-Lemeshow goodness-of-fit C statistic, 0.07 (area under the receiver operating characteristic curve = 0.74; 95% CI, 0.72–0.75).
