(A) DFS in 65 children with ALL. The broken line represents survival in patients with clonal diversity (n = 26), and the solid line represents survival in patients without clonal diversity (n = 39). (B) DFS in 56 patients with standard-risk ALL. The broken line represents survival in standard-risk patients with clonal diversity (n = 20), and the solid line represents survival in standard-risk patients without clonal diversity (n = 36).
