The institutional affiliation (organization and address) of the authors are submitted by the publisher. This data is not standardized, verified or maintained by NLM. Before 2014, only the first author's affiliation was included.
- Use [ad] to qualify affiliation or address of the author. Because variations occur in how affiliations are written, search the significant words of the institution or location, combined with AND.
cleveland[ad] AND clinic[ad]
