Kaplan-Meier curves for TTP and OS in the cytogenetic abnormality groups. The vertical axis represents the percentage of patients with disease progression (A,C,E,G) or the percentage of patients surviving (B,D,F,H). (A-B) TTP and OS for patients with or without del(13q). (C-D) TTP and OS for patients with or without t(4;14). (E-F) TTP and OS for patients with or without del(17p13). (G-H) TTP and OS for patients with or without t(4;14) matched pairs. CI indicates confidence interval; and HR, hazard ratio.
