Systematic searching in MEDLINE
MEDLINE contains more than 30 million references to journal articles in life sciences with a concentration on biomedicine. MEDLINE's comprehensive search functionality allows the user to develop a complex but sensitive systematic literature search. It is the recommended database to finalise your search strategy before repeating the search in your other chosen health databases.
