Measurement of the Red Blood Cell Distribution Width Improves the Risk Prediction in Cardiac Resynchronization Therapy

Figure 5

Improved discrimination of the prediction models. The improved discrimination capacity is graphically visualized by means of a box and whiskers diagram. The median (red line) of the mortality risk decreases in patients categorized as future survivors and increases in patients likely to die. The dotted line indicates the baseline risk. RDW = red blood cell distribution width; NT-proBNP = N-terminal pro-B-type natriuretic peptide.
