To the Editor On behalf of my coauthors, I report that it has come to our attention that there were unintentional statistical errors in our Original Investigation, “Decadelong Profile of Women in Ophthalmic Publications,” published in JAMA Ophthalmology online on November 13, 2014, and in the March 2015 print issue.1 The errors affect some of the data reported in the original article (some of the percentage differences, 95% CIs, and associated P values), but they do not affect the primary conclusions of the study, which indicated an increase in women first and last authors of original articles published in 3 ophthalmology journals between the years 2000 and 2010, but no such increase in women authors of editorials published by these journals during this time.
