| 3 February 2012 | Review declared as stable | This review will not be updated until at least 2016 or until new studies are available to be included. The last official search was run in December 2009 and we are not aware of any studies that have been made available since that date. |
| 24 December 2009 | New search has been performed | New search was conducted in December 2009. Three studies have been included (Clark 2008; Likar 2008; Wildiers 2009) one of which had been reported as an 'ongoing study' (Wildiers 2007) in the original Review. No new analysis has been possible. Conclusions have not changed but have been reinforced by the new studies. The text on results and discussion have been revised accordingly. |
