1. Subheadings - two particularly useful:
-
- /statistics & numerical data (/sn)
- In PubMed: "MeSH term/statistics and numerical data"[MeSH]; or, "statistics and numerical data"[subheading] for free-floating subheading searches. In PubMed, "statistics and numerical data" as a subheading explodes by default in PubMed to include the narrower subheadings "epidemiology"[subheading] - which includes "ethnology"[subheading] OR "mortaility"[subheading] - OR "supply and distribution"[subheading] (however, the subheading will not explode if [mesh:noexp] is used).
- In Ovid MEDLINE: MeSH term/sn (statistics and numerical data); or, sn.fs. for free-floating subheading searches - Used with non-disease headings for the expression of numerical values which describe particular sets or groups of data. It excludes supply or demand for which "supply and distribution" is used.

- Year introduced: 1989
-
- /mortality (/mo)
- In PubMed: "MeSH term/mortality"[MeSH]; or "mortality"[subheading] for free-floating subheading searches. For deaths resulting from various procedures statistically but for a death resulting in a specific case, use "FATAL OUTCOME"[MeSH], not "MeSH term/mortality"[MeSH].
- In Ovid MEDLINE: MeSH term/mo (mortality); or mo.fs. for free-floating subheading searches - Used with human and veterinary diseases for mortality statistics. For deaths resulting from various procedures statistically but for a death resulting in a specific case, use FATAL OUTCOME/, not /mo.
