Leukemia-free and overall survival. (A) The 5-year probability of leukemia-free survival for AML in the validation subset stratified by low (78%; 95% CI, 59-93), intermediate (53%; 95% CI, 47-60), high (40%; 95% CI, 32-49), and very high (25%; CI, 16-34) risk groups. (B) The 5-year probability of overall survival for AML in the validation subset stratified by low (80%; 95% CI, 59-95), intermediate (64%; 95% CI, 57-70), high (50%; 95% CI, 41-59), and very high (33%; 95% CI, 24-44) risk groups. (C) The 5-year probability of leukemia-free survival for ALL in the validation subset stratified by low (68%; 95% CI, 62-75), intermediate (51%; 95% CI, 46-57), and high (33%; 95% CI, 18-51) risk groups. (D) The 5-year probability of overall survival for ALL in the validation subset stratified by low (73%; 95% CI, 67-79), intermediate (62%; 95% CI, 56-67), and high (42%; 95% CI, 25-60) risk groups.
