This specialized search is intended for clinicians and has built-in search filters. Once you run your initial search, five study categories--therapy, diagnosis, etiology, prognosis, and clinical prediction guides--are provided to help you refine. You may also indicate whether you wish your search to be broad (i.e., include most relevant articles but probably including some less relevant ones) or narrow (i.e., including mostly relevant articles but probably omit a few).
