Figure 1: Failure curve (reaching HCT >50%). Failure curve represents time until the development of polycythemia defined as HCT >50%. As can be seen, the estimated rate of polycythemia at 6 months is 10.4%, at 12 months is 17.3%, at 18 months is 23.7%, and at 24 months is 30.2%. As patients are censored, or removed from analysis after achieving HCT >50%, the numbers above the X-axis represent the remaining cohort being analyzed at each time point. HCT: hematocrit.
