Details

In Process and publisher-supplied records lack MeSH terms. See the MeSH home page https://www.nlm.nih.gov/mesh/meshhome.html for additional information about MeSH. Note that more recent records may lack MeSH headings.

Value

List by Pubmed article. Each list contains a data frame with Heading and Type. The Heading is a MeSH Term and Type is either a Descriptor or a Qualifier of a Descriptor term. Qualifiers of a Descriptor immediately follow the Descriptor term in the data frame. When MeSH headings have not been included with a MEDLINE record, the list will contain NAs (see details).
