Citations within Clinical Evidence

Citations are brought to you by the BMJ Evidence Centre and incorporates the McMaster PLUS email surveillance system to collect and review the best evidence from the medical literature published since the last Clinical Evidence systematic search for a given review.

Users of citations with interests in a specific clinical problem or treatment are also invited to use Evidence Updates (, an openly accessible service, to look up topics covered in the McMaster PLUS database published as far back as 2002.

Updates based on the following processes conducted by McMaster PLUS:

  • systematic review of over 120 journals (including quarterly updates of the Cochrane Library) with selection of articles by expert research staff concerning the cause, course, diagnosis, prediction, prevention, and treatment of health problems, quality improvement and health economics, according to explicit criteria, with high reproducibility and periodic quality assurance checks.[1]
  • ratings of each eligible article for clinical relevance and newsworthiness made by at least 3 practitioners for each discipline for which the article might be pertinent. The McMaster Online Rating of Evidence (MORE) rating panel has over 3000 participants from around the world, all in clinical practice, with about half in primary care and the rest in internal medicine and its specialties, pediatrics, psychiatry, obstetrics, gynecology, and surgery.
  • e-mail alerts about new evidence. Each alert includes MORE clinical ratings and comments and electronic links to the article's abstract via PubMed (if available) and full text article link via PubMed or the publisher's site (if available for free).
