Most tables are derived from the MEDLINE XML files, parsed according
to the MEDLINE®PubMed®
XML Element Descriptions and their Attributes. The
source column indicates the corresponding element in the
MEDLINE XML. All elements other than those for the pmid_status table and
the citation table are nested within the PubmedArticle element. “attr”
indicates a named attribute in the XML, and “int position” indicates an
integer to index each item in a list. The citation table is derived from
the NIH
Open Citation Collection.
