This Feature contains some inaccuracies in the numbering of its references (BMJ 2013;346:f3159, doi:10.1136/bmj.f3159). The reference at the end of paragraph 11 should have read reference 7, rather than 6. In paragraph 12, the reference at the end of the first sentence should have been reference 8 (not 7). At the end of paragraph 17 the reference should have been reference 9 (not 8), and the reference at the end of the second sentence in paragraph 19 should have also been reference 9 (not 8).
