4 July 2008	Amended	We have converted this review to new review format.
1 September 2006	New search has been performed	A new search run in September 2006 revealed 7 references to studies already included in the review.
8 August 2006	New citation required and conclusions have changed	This review was updated with the addition of 7 new studies (Criner 1999; Geddes 2000; Goldstein 2003; Hillerdal 2005; Miller 2005; NETT 2003; Stammberger 2000). Most randomised participants were drawn from 1 large multi‐centre trial. Altered review conclusions stated that LVRS conferred benefit in the long term in terms of exercise capacity and quality of life in surviving patients, but that in the short term, risk of death within 3 months of surgery was increased. By the end of follow ‐up, risk of death was not significantly different. The subgroup of participants at greatest risk of postsurgical death had particularly low lung capacity, and risk of death in these patients was significantly higher at all time points.
