Evaluation of Image-Defined Risk Factor (IDRF) Assessment in Patients With Intermediate-risk Neuroblastoma: A Report From the Children's Oncology Group Study ANBL0531

Children's Oncology Group (COG) study ANBL0531 prospectively examined institutional determination of IDRF status and compared that to a standardized central review.
