Error in Abstract

JAMA Oncol. 2015;1(4):544. doi:10.1001/jamaoncol.2015.2066

In the Original Investigation titled “Correlation of Smoking-Associated DNA Methylation Changes in Buccal Cells With DNA Methylation Changes in Epithelial Cancer” published online May 14, 2015, in JAMA Oncology (doi:10.1001/jamaoncol.2015.1053), an error appeared in the last sentence of the abstract Results. The text “area under the curve, 0.88; 95% CI, 0.76-1.00” should be deleted from the parenthetical phrase so that the sentence reads “The corresponding area under the curve of a smoking signature derived from blood cells was lower than that derived from buccal cells in 14 of 15 cancer types (Wilcoxon signed rank test, P = .001).” This article was corrected online.
