This specialized search is intended for clinicians and has built-in search "filters." Four study categories--therapy, diagnosis, etiology, prognosis--are provided, and you may indicate whether you wish your search to be more sensitive (i.e., include most relevant articles but probably including some less relevant ones) or more specific (i.e., including mostly relevant articles but probably omit a few).
