Begrense et søk i PubMed til artikler som er Epub ahead of print


Dersom man kjører et søk i "Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily and Ovid MEDLINE(R) 1946 to Present" istedet for vanlig Ovid Medline, vil tilleggsverdien av å søke i PubMed begrense seg til artikler som er «Epub ahead of print».

For kun finne disse artiklene i PubMed kombinerer man søket med AND pubstatusaheadofprint.

For eksempel: diabetes[tiab] AND pubstatusaheadofprint
