Data from: Sharing detailed research data is associated with increased citation rate

Sharing research data provides benefit to the general scientific
community, but the benefit is less obvious for the investigator who makes
his or her data available. We examined the citation history of 85 cancer
microarray clinical trial publications with respect to the availability of
their data. The 48% of trials with publicly available microarray data
received 85% of the aggregate citations. Publicly available data was
significantly (p = 0.006) associated with a 69% increase in citations,
independently of journal impact factor, date of publication, and author
country of origin using linear regression. This correlation between
publicly available data and increased literature impact may further
motivate investigators to share their detailed research data.
