Contributions of authors
Contribution to the first published version (2006):
Wee‐Shiong Lim led the review team, screened the search for studies, and took the lead in drafting the manuscript. Julie Gammack and Jan Van Niekerk assisted in searching for studies and sought to identify studies for inclusion by screening the search results. All authors provided intellectual input into the final version of the review.
Contribution to the 2012 update:
Emma Sydenham (ES), Wee‐Shiong Lim (W‐S L), and Alan Dangour (AD) screened the search results and selected studies for inclusion. AD contacted experts in the field, sought additional data from included study investigators, and re‐wrote the Background section. ES contacted omega‐3 manufacturers for additional data; the data were reviewed by AD and W‐S L. ES extracted data from the study reports, entered the data into RevMan, assessed the risk of bias in included studies, undertook the analysis, and updated the text of the review; W‐S L checked for accuracy. All authors contributed to the final version of the manuscript. No sources of support are listed as all authors contributed to this review in their own time.
Declarations of interest
Alan Dangour is the principal investigator of Dangour 2010 (the Older People And n‐3 Long‐chain polyunsaturated fatty acids (OPAL) study).
ES and W‐S L: None known.

Differences between protocol and review
The methods of the review were updated to comply with the most recent version of the Cochrane Handbook for Systematic Reviews of Interventions (Version 5.1 March 2011) and the Cochrane Collaboration's Methodological Expectations of Cochrane Intervention Reviews criteria (November 2011).
The analysis of secondary outcomes was changed from mean change from baseline to difference between intervention groups at final follow‐up (Handbook section 7.7.3.1).
The secondary outcomes health‐related quality of life, depression, and anxiety which are listed in the protocol have been removed from this review. These outcomes have been assessed elsewhere (Appleton 2010).
Notes
Future updates of this review will include participants age 50 years and over.
