Systematic reviews of research evidence constitute a more appropriate source of research evidence for decision-making than the latest or most heavily publicized research study. Advantages of systematic reviews include

Broad syntheses of reviews

Broad syntheses of reviews are summaries of systematic reviews that address broad questions using systematic methods to

Evidence-based policy briefs

Evidence-based policy briefs bring together ‘global’ research evidence (from systematic reviews) and local evidence to inform deliberations about health policies and programmes


Primary studies in Epistemonikos include all of the studies that met the inclusion criteria for the systematic reviews in Epistemonikos.

The only limitations for inclusion of primary studies in Epistemonikos are those that were established by the review authors. We have not excluded studies based on publication status, language of publication, year of publication or study design beyond whatever exclusion criteria were used by the review authors.


Structured summaries of broad syntheses, systematic reviews and primary studies are prepared using standard headings and include critical appraisal and interpretation of the evidence that is summarised.

Typically these are prepared by someone other than the authors of the reports that are summarised and they contain more information than what is normally found in the abstracts written by the authors, which are also included in Epistemonikos.

The structured summaries that are included were not prepared specifically for Epistemonikos and are only available when they have been prepared by the authors of a report (e.g. executive summaries of evidence-based policy briefs) or by others (e.g. SUPPORT Summaries of systematic reviews for policymakers or DARE abstracts of systematic reviews).

Epistemonikos Dolmen

The dolmen (as you would have noticed, we love funny words), is a diagram based in the principles of Evidence-Based Health Care where we believe everything people calls evidence can be classified. It is the conceptual framework of epistemonikos and allows many of the functionalities of Epistemonikos.

The original diagram did include 5-categories and resembled a neolitic dolmen. The diagram was simplified afterwards into a 3-categories diagram, but the name persisted. Don’t know what a dolmen is?, go to Wikipedia. Want to see more dolmens?, go to Pinterest.
