An enhancement has been added to PubMed whereby the terms entered in the strategy are bolded so users can see where they appear in the search results.  Terms are bolded in the Summary display format.

Also bolded will be terms that PubMed has added to expand your search.  For example, if you enter “tumour,” the term, “tumor” will also be searched.  If  “tumor” appears in the Summary display format of any references retrieved, it also will be bolded.  The terms PubMed adds to the search can be seen in “Search details” on the right-hand side of the results page.  See an example here.
