A Nomogram to Predict Prognostic Value of Red Cell Distribution Width in Patients with Esophageal Cancer

Figure 4

A nomogram predicts survival prediction based on RDW and other prognostic factors in patients with ESCC. The nomogram is used by totalling the points identified at the top of the scale for each independent factor. This total point score is then identified on the total points scale to determine the probability of risk prediction. Harrell’s c-index for CSS prediction was 0.68. For example, a female (9 points) patient aged 60 years (38 points) with T2 (33 points), N1 (31 points), and RDW 14.5% (33 points) would score 144 total points which converts to a risk probability for death of 57%.
