Red cell distribution width in anemic patients undergoing transcatheter aortic valve implantation

Figure 2 Regression analysis for risk factors associated with anemia. A: Classification tree with significant node-splits and distribution of patients with anemia. A creatinine > 1.1 mg/dL (P < 0.001) and age > 83 (P = 0.027) were found to be statistically relevant risk factors for anemia; B: Logistic regression with all covariables which were supposed to be associated with anemia. Forest plot with odds ratios and 95%CI (logarithmic scale); C: Logistic regression with the best selected covariables using AIC. A creatinine > 1.1 mg/dL (P < 0.001) and age > 83 (P = 0.001) were found to be statistically relevant risk factors for anemia. a: Years; AIC: Akaike information criterion; CAD: Coronary artery disease; CKD: Chronic kidney disease; Crea pre: Creatinine (mg/dL) preoperative; DM: Diabetes mellitus; LVEF: Left ventricular ejection fraction (%).
