Each study included in a NEL systematic review receives a quality rating of positive, neutral, or negative, based upon a predefined scoring system. The appraisal of study quality is a critical component of the systematic review methodology because in a highly transparent manner, it indicates the relevance (external validity/generalizability) and validity of each study’s results.
Research Design and Implementation (RDI) Checklists (Dietary Patterns)
The Research Design and Implementation Checklist: Primary Research includes 10 validity questions based on the AHRQ domains for research studies. Sub-questions are listed under each validity question that identify important aspects of sound study design and execution relevant to each domain. Some sub-questions also identify how the domain applies in specific research designs.
