 The study investigates the citation benefit of making gene expression microarray data publicly available. The authors found that studies with publicly available data received a higher number of citations than similar studies without available data, even after controlling for other factors known to affect citation rate. The citation benefit varied over time and was highest for papers published in 2004 and 2005. The study also found that third-party data reuse was high and increased steadily since 2003. Overall, the findings suggest that making gene expression microarray data publicly available can have a positive impact on citation rate and that data set reuse is an important factor contributing to this benefit.
