Demographic, treatment history, and intellectual performance of each group.

Note: RT = survivors who received radiation treatment with or without chemotherapy, NRT = survivors who did not receive radiation treatment. Groups were similar across demographic variables. *: Variables with significant group difference (p < .05). a,b: Different superscripts (e.g., a and b) signify significant mean differences between groups (χ2, p < .05), whereas matching superscripts illustrate similar means (e.g., b and b). RT group had significantly more individuals treated with chemotherapy and individuals identified with hormone deficiency. Across most cognitive tasks and indices, the RT group was significantly lower relative to both NRT and HC groups; in contrast, the NRT group was similar to controls. IQ Mean = 100, SD = 15; Subtest T Score Mean = 50, SD = 10. Demographic, treatment history, and intellectual performance of each group.
