In the August 2012 issue, the article entitled “Nurses on trial” (Nat. Med. 18, 1165–1167, 2012) incorrectly stated that 27% of people who received talk therapy after a stroke suffered from depression one year on. The correct percentage was 52%. Furthermore, the story reported that 48% of individuals on antidepressants alone were afflicted one year later, when in fact this was 73%. The errors have been corrected in the HTML and PDF versions of the article.

The November 2012 issue's “Biomedical briefing” (Nat. Med. 18, 1600–1601, 2012) misspelled Madhav Thambisetty's first name as Madhev and incorrectly stated his location as Bethesda, Maryland, when he is actually based in Baltimore. The error has been corrected in the HTML and PDF versions of the article.

The table accompanying the article “New biologic drugs get under the skin of psoriasis” (Nat. Med. 18, 638, 2012), which appeared in the May 2012 issue, misstated that the Novartis drug secukinumab was in phase 2 when in fact it was in phase 3. The error has been corrected in the HTML and PDF versions of the article.

In the November 2012 print issue, the article entitled “Call in the backup” (Nat. Med. 18, 1602–1605, 2012) contained a table in which the Nationwide Children's Hospital's SMN gene therapy strategy was misplaced in the wrong category. SMN gene therapy was also mislabeled as SMN1 gene therapy. The table was correct in the HTML and PDF versions of the article online.
