  1. The percent disease-free survival (DFS) probability for each NPI group was calculated for 60 and 120 months, standard errors are included in parenthesis. The 95 % Confidence Intervals (CI) for the difference in survival probability for ≤3.4 vs 3.4 to 5.4 and 3.4 to 5.4 vs >5.4 for each time-point are listed
