 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 many variables known to predict citation rate. The citation benefit varied with date of dataset deposition and was highest for papers published in 2004 and 2005. Data reuse was high, with an estimated 20% of datasets deposited between 2003 and 2007 being reused at least once by third parties. The authors conclude that a substantial fraction of archived datasets are reused and that the intensity of dataset reused has been steadily increasing since 2003.
