Integrating information from the lower levels of the hierarchy with individual patient records, systems represent the ideal source of evidence for clinical decision-making. An example of a system in this context would be a Clinical decision support system (CDSS).
Summaries are regularly updated clinical guidelines or textbooks that integrate evidence-based information about specific clinical problems

Synopses of syntheses, summarize the information found in systematic reviews. By drawing conclusions from evidence at lower levels of the pyramid, these synopses often provide sufficient information to support clinical action.
Commonly referred to as a systematic review, a synthesis is a comprehensive summary of all the evidence surrounding a specific research question.
Updated quarterly, it includes The Cochrane Database of Systematic Reviews (complete reviews as well as protocols of reviews inprogress), Database of Abstracts of Reviews of Effectiveness (citations to other systematic reviews produced outside of the Cochrane Collaboration), The Cochrane Central Register of Controlled Trials, and The Cochrane Database of Methodology Reviews (a bibliography of articles on the science of research synthesis), Health Technology Assessment, and NHS Economic Evaluation Database.
The EPCs review all relevant scientific literature on clinical, behavioural, and organization and financing topics to produce evidence reports, technical reviews (covering nonclinical methodological topics), and technology assessments.
Synopses of single studies summarize evidence from high-quality studies. The following evidence-based abstract journals are the best place to find this type of information:
Studies represent unique research conducted to answer specific clincial questions.
Controlled Vocabulary Databases - use subject headings for high-specificity searching
Grey Literature is any literature that has not been published through traditional means. It is often excluded from large databases and other mainstream sources.
