Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
416 participants were enrolled between 9/9/2003 and 3/7/2013.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Of the 416 participants enrolled, three were ineligible and taken off study.

Reporting Groups
  Description
Average-Risk Group Participants assigned to the average-risk arm had localized tumor without overt evidence of invasion beyond the posterior fossa (or supratentorial compartment for PNET's/ATRT). Participants with T4 disease met the following criteria: gross total resection defined as residual tumor or imaging abnormality whose size was <1.5 cm^2 on postoperative CT or MR images, no evidence of CNS or extraneural metastasis, and brain stem invasion by the tumor in the absence of imaging evidence of residual tumor (tumor size <1.5 cm^2).
High-Risk Group Participants assigned to the high-risk arm were determined to have the presence of metastatic disease within the neuraxis (i.e., evidence of subarachnoid dissemination), OR presence of residual disease (≥1.5 cm^2) at the primary site after surgery.

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
Participants had a diagnosis of medulloblastoma, supratentorial primitive neuroectodermal tumor (PNET), PNET variants (ependymoblastoma, pineoblastoma, CNS neuroblastoma), or atypical teratoid rhabdoid tumor (ATRT).
