If you are looking for a few highly relevant articles on a subject, consider using the PubMed Best Match feature, available in the Sort menu.
Best Match uses machine learning to rank the results by relevance and present the best matches at the top (see technical details in a paper by Fiorini N, Canese K, Starchenko G et al., PLoS Biol. 2018). View the Best match search information in the right column to see mapped MeSH terms. Click See more to view additional synonyms.
Note that Best Match is a slightly different search, using the new PubMed system. You may retrieve slightly different results from this search because of added synonyms, plurals and British/American spelling variants.
