For this study, EPA analyzed the miRNA PCR data that were used for Figures 4 and 5 of the data. The raw PCR data itself, which were not generated by EPA, are included as zipped RDML files. These data include amplification data for all miRNA targets and samples measured. Version 2 of these datasets have been updated to include new analyses (Mann Whitney U Test to include a non-parametric stat in response to reviews).
