This glossary includes over 4,000 terms for use in informed consent forms and discussions. Use the definitions to replace or clarify terms that may be unfamiliar to study subjects. The definitions are very simplified and may not be appropriate for a specific context. Therefore, do not use a definition unless you understand the meaning of the original term. More complete definitions of clinical research terms are in the Glossary for Clinical Research.
|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".
||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”.
|Include definitions in search
||Search on both the terms defined and their definitions.
|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 terms, this option allows you to search only amongst the terms 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.
- Results are displayed in this order: (1) defined terms that begin with the search term, (2) defined terms that include the search term, (3) descriptions that include the search term, (4) descriptions that include a word or phrase that begins with the search term, and (5) all other results.
- Searching on a single letter finds only acronyms, credentials, and prescription abbreviations.
- 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.
- Clicking on a blue underlined term initiates a search on that term.
- Search terms that are singular and present-case with U.S. English spelling are more likely to find results.
