  3. Ovid: Bibliographic Databases • MEDLINE

  4. Produced by the National Library of Medicine Indexes over 4,700 journals from the mid-1960’s forward Controlled vocabulary (MeSH) available Premier bibliographic database for information in the fields of medicine, dentistry, veterinary medicine, nursing, the healthcare system, and preclinical sciences International in scope MEDLINE

  5. Clinical Trial, Phase I-IV Controlled Clinical Trial Randomized Controlled Trial Evaluation Studies Meta-Analysis Multicenter Study Practice Guideline Publication Types
