  2. Results of the comparison of Disease Free Survival (DFS) curves of transplanted patients (n=30) and matched chemotherapy controls (n=130) are reported. Global p-values are shown for Fisher and Tippett second order statistics based on the distance of DFS curves (TSi 1) or their transformation (TLSi 1) and for different choices of the time points (fixed or points at 10-90th percentiles (perc) or 80% of all the observed event times (all)).
