What was measured

The two-year event-free survival will be compared with a standard established from adult oncology data and the results of POG-9486. The two-year Kaplan-Meier estimate of event-free survival will be compared with 70% using a 1-sided test of size 0.05 using the asymptotic distribution of the complementary log-log distribution of the estimate.

Analysis population: No patients were enrolled to Stratum 1.
