title: Research methodology search filters: are they effective for locating research for evidence-based veterinary medicine in PubMed?
abstract: OBJECTIVE
  The study examined the effectiveness of research methodology search filters developed by Haynes and colleagues and utilized by the Clinical Query feature of PubMed for locating literature for evidence-based veterinary medicine (EBVM).
  
  
  METHODS
  A manual review of articles published in 6 commonly read veterinary journals was conducted. Articles were classified by format (original study, review, general article, conference report, decision analysis, and case report) and purpose category (etiology, prognosis, diagnosis, and treatment). Search strategies listed in PubMed's Clinical Query feature were then tested and compared to the manually reviewed data to calculate sensitivity, specificity, and precision.
  
  
  RESULTS
  The author manually reviewed 914 articles to identify 702 original studies. Search #1 included terms determined to have the highest sensitivity and returned acceptable sensitivities over 75% for diagnosis and treatment. Search #2 included terms identified as providing the highest specificity and returned results with specificities over 75% for etiology, prognosis, and treatment.
  
  
  CONCLUSIONS
  The low precision for each search prompts the question: Are research methodology search filters practical for locating literature for the practice of EBVM? A study examining terms related to appropriate research methodologies for advanced clinical veterinary research is necessary to develop filters designed to locate literature for EBVM.
