For the CCG 1953 study, N = 115; for the CCG 1883 study, N = 135.
*
For some variables, some data were not submitted for individual patients (liver size, race, CNS, CD10), so totals do not add up to 115.
†
11q23 info for 1883 is based solely on karyotypes accepted by central review. Information was not complete on all 135 patients. Percentages were calculated excluding patients for whom data were unknown.
