Key Research Summaries

Follow the links in the left-hand navigation to access summaries of the research evidence upon which the information in this site is based. A full list of sources, including full references for the sources of information we have not yet summarised, is available on the cited references page.

Abstracts of most clinical studies can also be located and obtained for free from PubMed (the US National Library of Medicine) by typing the study details into the PubMed single citation tracker.

Study summaries are organised here according to date of publication. New studies will be added as they are published, and selected older studies will be added as we summarise them.
