Clinical Evidence (BMJ)

Clinical Evidence is an international decision support resource for the practice of evidence-based medicine (EBM). It publishes peer-reviewed systematic reviews of important clinical conditions, which summarize the current state of knowledge and uncertainty about the prevention and treatment of common clinical conditions in primary and hospital care, based on searches and appraisal of the literature. Each systematic review (SR) contains a page that lists key clinical questions and interventions and describes whether they have been found to be effective or not. However, fitting interventions into categories of effectiveness is not always straightforward; the categories represent a mix of several hierarchies: the size of benefit (or harm), the strength of evidence (RCT or observational data), and the degree of certainty around the finding (represented by the confidence interval [CI]). Clinical evidence also tries to indicate whether studies are done between two different interv entions or between a placebo and an intervention, and whether a study was only done with a specific group of people.
