Although systematic and explicit, existing evidentiary criteria for clinicalguidelines tend to use study design as a surrogate for evidence quality.Moreover, they do not independently characterize evidence quality and netbenefits and do not systematically evaluate research needs. Decision analysis,which quantifies the range of potential net benefits based on whatever evidenceis available, can augment traditional frameworks. It is particularly useful forpediatric research, where randomized controlled trials are often unavailable and infeasible. Policymakers should incorporate decision analysis into comparativeeffectiveness research and clinical guidelines.
