In an article about cervical cancer mortality in Canada by Edward Ng and associates,1 the 3-year moving mortality averages were based on data obtained from the International Agency for Research on Cancer. The agency name was given incorrectly in the Methods section and in the cited reference (reference 9 in the original article). The correct information appears in the second reference2 in this correction.
