Probabilities of PFS and CCyR according to the criteria for failure at 3, 6, 12, and 18 months. Failure patients are represented by the dashed line and nonfailure patients by the continuous line. PFS curves start from 100%, and CCyR curves start from 0%. The number of patients in each category, the precise numerical values for the probabilities of PFS and CCyR, and the P values are shown in Table 2. Vertical lines represent censored patients (but the corresponding lines are not shown in the CCyR curves). At 18 months, 100% of the patients in the nonfailure group were in CCyR (by definition); thus, the curve is not shown.
