^aMeSH: Medical Subject Headings.

^bThe MeSH thesaurus contains qualifiers that can be linked to each keyword to make it more precise. For example, the index entry asthma can be specified by the qualifier diagnosis (asthma/diagnosis), to tell the reader that only the diagnosis of asthma is addressed in the article, and not its other aspects (treatment, complication, etc).
