Fig 4. Classification results are more impacted to relative abundance degradation at coarser taxonomic resolution.

Results on the 25 case-control shotgun studies by comparing the baseline (i.e., relative abundance profiles) with the presence/absence profile generated by thresholding at 0.0% and varying taxonomic resolution from species to order level. Difference in AUC between the presence/absence and the relative abundance RF classification result. A positive value indicates that presence/absence outperforms relative abundance data.
