"Grey literature" refers to formats that are not published in the traditional book/journal medium or indexed in bibliographic databases.
Studies have shown that articles with positive results from respected institutions by well-known authors in English or from a developed country are more likely to be published than other articles. Seeking grey literature helps ensure that the results of a comprehensive review are as objective and free from of this publication bias as possible. Formats include:
- Clinical Trials (US NIH)
- NIH RePORTER UF NIH-only trials. Search by project start/end date, funding mechanism, country, PI, publications. Results include link to "similar projects".
