Quantitative reverse-transcribed polymerase chain reaction results for BCR-ABL ratio after RISCT. (A) The patient trial numbers are listed in the first vertical column. Results shown are mean values for each completed 6-month period. To allow presentation of more recent data, the mean of the most recently completed 3-month period is also shown on the bars of patients 7, 13, 15, and 16. Arrows represent timing of DLI, and close vertical bars represent periods of IM therapy. The right-hand column shows the 2 most recent sequential results and is accompanied by the current follow-up time (in months) after transplant. Patient 4 died at 12 months and is not illustrated, as the single positive BCR-ABL result obtained during follow-up was not quantified; in all other samples, BCR-ABL transcripts were undetectable. This patient did not receive DLI. (B) Median BCR-ABL results over 6-month periods after RISCT. The number of patients for whom data were available at each time point is indicated above each column. Patient 4 is not included because, where a positive result was obtained, this was not quantified.
