Note: Referent in each case is RDW ≤13.3%. Estimates adjusted for age, sex, race, Deyo-Charlson index, patient type (surgical versus medical), CABG, MI, CHF, hematocrit, transfusion (from 48 hours prior to critical care initiation throughout the ICU stay), white blood count, MCV, blood urea nitrogen, and creatinine.
