The 6S Hierarchy of Evidence-Based Resources is a useful model for guiding clinical decision making.The model proposes six layers of evidence sources. The search for evidence-based resources should begin at the highest possible layer. The categories of EBM resources described here correspond to layers of the 6S model of EBM resources.
