The March 1, 2015, article by McCormick et al, entitled “RTOG 9804: A Prospective Randomized Trial for Good-Risk Ductal Carcinoma In Situ Comparing Radiotherapy With Observation” (J Clin Oncol 33:709-715, 2015), contained an error.
In Figure 2, in the legend, C and D were incorrect. C was given as “Disease-free survival (n = 585)” and D was given as “Overall survival (n = 585)” but it should have been reversed. The legend should have read, (C) Overall survival (n = 585). (D) Disease-free survival (n = 585).
The online version has been corrected in departure from the print. The authors apologize for the error.
