Computerized decision support systems. These are new and evolving technologies that allow clinicians to search for the best evidence from applicable research based on a given patient's individual history and presentation.
Summaries/Guidelines. These compile the best evidence from several of the lower layers of the pyramid (especially from syntheses or synopses of syntheses), and provide a wide range of treatment information. Examples include clinical practice guidelines, clinical pathways, summaries and guidelines in point-of-care tools, and evidence updates.
Synopses. If available on a given topic, these short synopses provide concise and useful descriptions of significant systematic reviews or meta-analyses.
Syntheses. A synthesis is a systematic review of all the literature on a given topic that that allows for a comprehensive summary of what is known. These may include meta-analyses which statistically pool data from individual studies.
Studies. These are original studies or journal articles (RCT, Cohort, Case Control Studies/Trials) and Case Series/Reports.
Expert Opinion/ Background. Examples include review articles, textbooks, point-of-care tools with topic summaries
