Single Citation Matcher is the easiest way to find an article for which you know all or part of the citation. A few key bits of information are often enough (e.g. author, journal, year) to find article citations. Access Single Citation Matcher under PubMed Tools on the PubMed home page or under the More Resources menu tab on the Advanced Search page.
The Clinical Queries section of PubMed (available under "PubMed Tools" on the PubMed home page) allows you to apply quick filters or “hedges” to your searches. Search filters are available in several categories including therapy, diagnosis, etiology and prognosis. There is a broad filter and a specific filter for each category.
