Erratum: Sex and Gender: Critical Variables in Pre-Clinical and Clinical Medical Research (Cell Metabolism (2016) 24(4) (203–209) (S1550413116303631) (10.1016/j.cmet.2016.07.017))

(Cell Metabolism 24, 203–209; August 9, 2016) As a result of an author oversight in the originally published version of this article, there were mathematical errors in the estimated number of persons in which gender identity does not match biological sex at birth. The original article stated that the number of estimated individuals for whom this applies was approximately 8 million people in the United States; this should have been stated as 800,000 people in the United States, or about 0.2%–0.3% of the population. The original article also stated that the prevalence could actually exceed 0.5% of the population, or ∼16 million people; the latter number should have been ∼1.6 million. Finally, the original article originally stated that, within the Veterans Health Administration, the incidence of transgender-related diagnoses increased by 76% from 2009 to 2013; this should have more accurately said that the incidence increased from 936 diagnoses in 2009 to 2,567 diagnoses in 2013. These errors have now been corrected in the article online. The authors apologize for these errors and any inconvenience this may have caused.
