What are MEDLINE Clinical Queries?

You can refine your search using specific search strategies designed to narrow your results in nine research areas: Therapy, Diagnosis, Prognosis, Reviews, Clinical Prediction Guides, Qualitative, Causation (Etiology), Costs, and Economics.

Three strategies are provided for each area:

  • High Sensitivity - the broadest search to include ALL relevant material. It may include less relevant materials.
  • High Specificity - the most targeted search to include only the most relevant result set, may miss some relevant materials.
  • Best Balance - retrieves the best balance between Sensitivity and Specificity.

Clinical Queries are created in collaboration with the Health Information Research Unit (HIRU) at McMaster University, and are designed for clinician use. For additional information about ongoing research, please visit
