The October 10, 2018, article by Winter et al entitled “Improved Survival for Children and Young Adults With T-Lineage Acute Lymphoblastic Leukemia: Results From the Children’s Oncology Group AALL0434 Methotrexate Randomization” (J Clin Oncol 10.1200/JCO.2018.77.7250) was published with errors.
In Figure 2:
-
• Panel B:
∘ “HD-MTX (n = 517)” should have been “HD-MTX (n = 512).”
-
• Panel C:
∘ “HD-MTX (n = 517)” should have been “HD-MTX (n = 512).”
In Figure 3:
-
• Panel A (for both DFS and OS graphs):
∘ “C-MTX (n = 311)” should have been “C-MTX (n = 54).”
∘ “HD-MTX (n = 307)” should have been “HD-MTX (n = 55).”
∘ “Hazard ratio, 2.441 (95% CI, 0.299 TO 12.585” should have been “Hazard ratio, 2.441 (95% CI, 0.473 to 12.59)."
-
∘ Below the graph, under No. at risk:
■ The first number of the first row was “311” but should have been “54.”
■ The first number of the second row was “307” but should have been “55.”
-
• Panel B (for both DFS and OS graphs):
∘ “C-MTX (n = 206)” should have been “C-MTX (n = 357).”
∘ “HD-MTX (n = 202)” should have been “HD-MTX (n = 350).”
-
∘ Below the graph, under No. at risk:
■ The first number of the first row was “206” but should have been “357.”
■ The first number of the second row was “202” but should have been “350.”
