Disease progression.
Probability of disease progression was indicated by the treatment-free interval in CD38+ (A) and CD38− (B) B-CLL patients subgrouped according to the expression of ribosomal and translation-associated genes identified by unsupervised cluster analysis (Figure 2). Kaplan-Meier plots compared time periods from diagnosis to initiation of chemotherapy. Statistical analysis was performed using the log-rank test.
