Significant differences in the comparison of human gut and mouse gut metagenomes. The five most statistically significant differences in numbers of reads assigned to taxon classes in the comparison of a human gut [16] and obese mouse gut [17] metagenomes. A positive support (proportion of deviation) indicates that the difference is in favor of the human gut dataset, whereas a negative sign indicates the opposite.
