PubMed Enhancements February 2019

The National Library of Medicine has announced several updates to enhance PubMed:
- Plain Language Summaries: PubMed will display plain language summaries when these summaries are supplied by the publisher. The plain language summary will appear below the abstract. They will also appear in the XML in the field and in the MEDLINE display with the label OAB.
- Reference Lists: In the past, reference lists have been included only in citation data coming from PubMed Central (PMC) articles. NLM now accepts reference lists supplied by publishers. Like the PMC reference lists, the publisher-supplied references will be available in the citation XML and they will display in PubMed Labs.
- Systematic Review [Publication Type]: Systematic Review [PT] was added to the 2019 MeSH vocabulary. NLM applied this publication type retrospectively to systematic review citations in PubMed as part of the annual MeSH update in December 2018. The search strategy for the Systematic Review filter was also updated to focus retrieval on citations to systematic reviews. This filter no longer retrieves other article types including meta-analyses, reviews of clinical trials, evidence-based medicine, consensus development conferences, or guidelines. This change is a response to user requests for a Systematic Review filter that returns only citations to systematic reviews. Users can apply the Systematic Review filter to a search from the left sidebar or by including systematic[filter] in the search. This filter is also used for Systematic Review retrieval in PubMed Clinical Queries.
Please note: The Systematic Review filter will retrieve broader results than searching for systematic review[pt]. The filter strategy also retrieves systematic review citations that have not been assigned the publication type; for example, citations that have not yet undergone MEDLINE indexing.
