What was measured

Percentages of patients with responses after radiation therapy (induction therapy) are reported with 95% confidence intervals. Complete and partial responses were considered responses.

Analysis population: 83 of 87 eligible Arm A medulloblastoma patients were evaluated for response after induction, as were 85/89, 48/53, and 55/56 arm B, C, and D patients, respectively.

Groups in this outcome

Regimen A (Medulloblastoma Patients)

Medulloblastoma patients who received regimen A (no carboplatin / no isotretinoin)

Regimen B (Medulloblastoma Patients)

Medulloblastoma patients who received regimen B (carboplatin / no isotretinoin)

Regimen C (Medulloblastoma Patients)

Medulloblastoma patients who received regimen C (no carboplatin / isotretinoin)

Regimen D (Medulloblastoma Patients)

Medulloblastoma patients who received regimen D (carboplatin / isotretinoin)

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
