Contributions of authors
Francine M. Ducharme reviewed the protocol design, supervised the literature search, reviewed all citations, participated in the selection of trials, methodology assessment, and data extraction, corresponded with authors and/or the pharmaceutical companies to identify other relevant trials, verify methodology and data extraction and request additional information, analysed and interpreted results of the meta‐analysis, and took part in writing up the final review.
Toby Lasserson (Update 2006 & 2008): Assessed studies for inclusion/exclusion, extracted & entered data, revised Results section.
Christopher Cates edited the review, checked the methodology, and contributed to writing up the final review.
Felix Ram participated in the initial version of the review (2005): protocol design, identified and reviewed the full‐text publication of all citations of potential or potentially eligible RCTs, extracted the methodology and data, analysed and interpreted results of the meta‐analysis, and wrote the first draft of the review.

Differences between protocol and review
In the protocol published in April 2001, we had planned to examine the impact of the inhaled glucocorticoids (subgroups 3) and of baseline severity (subgroups 5) as sensitivity analyses but changed it to subgroup analyses because it enhanced the clarity of interpretation. The last subgroup analysis (6), not initially considered in 2001, was added to the list subsequently as recent data indicated that the number of inhaler devices to deliver LABA + ICS might be an important effect modifier (Nelson 2003).
