Shown are raw frequencies and -on brackets- absolute gene numbers in common between each single chemical and the mixture, or unique in the mixture ("match"); raw frequencies and absolute common gene number with "same" and "opposite" trend between each single chemical and the mixture Frequencies in first column were calculated on the basis of the total gene number observed in the mixture (103 genes). In the other cases, these were computed with respect to the total number of DEGs (238)
