Demographic and Clinical Characteristics
Comparisons of demographic and clinical characteristics between survivors treated with XRT and PRT are displayed in Table 1. The XRT group was younger on average at diagnosis than the PRT group (p< 0.01). Reflecting the study design, the XRT group was further out from RT completion at the time of neurocognitive evaluation relative to the PRT group (p < 0.001). Both groups were made up of predominantly male survivors, and the majority of primary caregivers completed high school at a minimum. The majority of survivors in both groups underwent craniotomy and similar rates were treated with craniospinal radiation (60% of the XRT group and 55% of the PRT group).
