We have electronic gremlins too at the BMJ. This time they pushed off a note that should have appeared in the margin of this article by Jayne Parry and Andrew Stevens (17 November, pp 1177-82). The note would have alerted readers to the fact that additional references appear on bmj.com (these are cited in the main text as w1 to w17).
