PCR status refers to E2A-PBX1 chimeric transcripts and patients were classified as either never negative (no negative PCR assays from PB/BM samples available from weeks 25 and 31) or at least one negative and never positive (no positive PCR assays from PB/BM samples available from weeks 25 and 31) or at least one positive.
