Search Options:
Date Select one date or all dates.
Word or phrase Search on a word such as "adverse" or a phrase such as "adverse event".
Beginning of word Search on the beginning of a word. For example, searching on "investigat" finds "investigator" and "investigational", but not "subinvestigator".
Any text Search on text that may occur in the middle of a word or across words. For example, searching on "investigator" finds "subinvestigators"; searching on “to cha” finds “to chance”.
Punctuation is significant Limit results based on the presence or absence of punctuation. For example, searching on "FDA-approved" finds only "FDA-approved", while searching on "FDA approved" finds only "FDA approved". With this option unselected, searching on "crossover" will find both "crossover" and "cross-over".
Search within results below If your initial search returns too many results, this option allows you to search only among the results previously found.

  • Searches only find instances where the exact text in the search box is found. For example, searching for “event adverse” finds no results.
  • Surrounding a search phrase with quotation marks has no effect, unless you select "Punctuation is significant".
  • Words such as “and” and “or” are interpreted as part of the search phrase.
  • Red underlining indicates where the search term has been found in the title. Searches in the body of the article are not shown.
  • Search terms that are singular and present-case with U.S. English spelling are more likely to find results.
