Osonnaya C, Osonnaya K, Abdi M, et al. Effect of Helicobacter pylori eradication on dyspepsia, quality of life and utilisation of health care resources in the Eastern England Helicobacter Pylori project: randomised control trial (Gut 2007;56(Suppl II):A16.

It has come to the editor's notice that the wording of this abstract closely resembles that of an article published in the BMJ (Lane J A, Murray L J, Noble S, et al. Impact of Helicobacter pylori eradication on dyspepsia, health resource use, and quality of life in the Bristol Helicobacter project: randomised controlled trial. BMJ 2006;332:199–204). We therefore wish to withdraw the abstract by Osonnaya et al.

We also wish to withdraw the following abstracts, which closely resemble previously published articles by other authors.
