Welcome to Clinical Evidence, the international source of the best available evidence on the effects of common clinical interventions.

Clinical Evidence is a new kind of decision-support resource. At our heart is an international peer reviewed journal publishing systematic reviews of important clinical conditions, but Clinical Evidence goes well beyond the boundaries of a conventional journal. We constantly update our reviews and integrate them with a range of additional evidence based medicine (EBM) resources to create a powerful support tool, providing busy clinicians with access to the very latest and most relevant medical knowledge for treatment decisions. It is owned by BMJ Publishing Group Limited, a private limited company, incorporated in the United Kingdom, company registration number 3012371. Their registered office is situated at BMA House, Tavistock Square, London WC1H 9JP. VAT Number 674738491.

Clinical Evidence systematic reviews summarise the current state of knowledge and uncertainty about the prevention and treatment of clinical conditions, based on thorough searches and appraisal of the literature. It is neither a textbook of medicine nor a set of guidelines. It describes the best available evidence from systematic reviews, RCTs, and observational studies where appropriate, and if there is no good evidence it says so.
