Red Cell Distribution Width and Mortality in Newly Hospitalized Patients Sabina Hunziker, MD, MPH, Jennifer Stevens, MD, MS, Michael D. Howell, MD, MPH The American Journal of Medicine Volume 125, Issue 3, Pages 283-291 (March 2012) DOI: 10.1016/j.amjmed.2011.08.021 Copyright © 2012 Elsevier Inc. Terms and Conditions

Figure 1 Unadjusted and adjusted risk of mortality within red cell distribution width deciles (top). Risk of mortality from multivariate logistic regression analysis adjusted for age, gender, race, and all comorbidities (bottom) (Table 2). Red cell distribution width deciles refers to the following red cell distribution width ranges: <12.9%, 12.9%-13.2%, 13.3%-13.5%, 13.6%-13.8%, 13.9%-14.1%, 14.2%-14.5%, 14.6%-15.0%, 15.1%-15.8%, 17.1%, and >17.1%. RDW = red cell distribution width; OR = odds ratio; CI = confidence interval. The American Journal of Medicine 2012 125, 283-291DOI: (10.1016/j.amjmed.2011.08.021) Copyright © 2012 Elsevier Inc.

Figure 2 Subgroup analysis for association of red cell distribution width and mortality. Risk for mortality (OR and 95% CI) derived from multivariate logistic regression analysis adjusted for age, gender, race, and all comorbidities within different subgroups. OR>1 refers to a positive association of high red cell distribution width and mortality. OR<1 refers to a negative association of high red cell distribution width and mortality. RDW = red cell distribution width; CI = confidence interval. The American Journal of Medicine 2012 125, 283-291DOI: (10.1016/j.amjmed.2011.08.021) Copyright © 2012 Elsevier Inc. Terms and Conditions

Figure 3 Unadjusted and adjusted risk of intensive care unit transfer within red cell distribution width deciles (top). Risk of intensive care unit transfer from multivariate logistic regression analysis adjusted for age, gender, race, and all comorbidities (bottom) (Table 2). Red cell distribution width deciles refers to the following red cell distribution width ranges: <12.9%, 12.9%-13.2%, 13.3%-13.5%, 13.6%-13.8%, 13.9%-14.1%, 14.2%-14.5%, 14.6%-15.0%, 15.1%-15.8%, 17.1%, and >17.1%. ICU = intensive care unit; RDW = red cell distribution width; CI = confidence interval; OR = odds ratio.
