Fig 5. Frequencies of sharing modalities in the four genetic research fields analyzed.

Rates of usage of different sharing modalities based on the inspection of papers indexed in Medline from 01/01/2008 to 31/12/2011. The total number of scrutinized datasets for each field of research is reported in parentheses. It should be noted that the modality “will provide on request” was observed only by Milia et al. [32].
