If your search retrieved too few citations, here are three strategies to expand your search.
1. Find related articles. Open a useful citation in abstract view, then click the Similar articles "See all" link to display a pre-calculated set of PubMed citations closely related to the article.
2. Try alternative search terms to the ones you used. Try to find a MeSH term for your topic. (Learn more.)
The search for 'parental bonding NICU' brings up fewer than 40 articles. However, the search for 'parent-child relations neonatal intensive care unit' retrieves over 400. See how PubMed ran this search in the details box below.
Adding a term, such as breastfeeding or holding will retrieve a very specific smaller subset of useful articles the first search missed.
3. Remove extraneous or specific terms to broaden your search.
