Fig. 2: Relative abundances of microbiota before, during and after chemotherapy.

A Relative abundances of different phyla before AC-D (n = 44), during AC (n = 43), during D (n = 29) and after AC-D treatment (n = 37). B Composition plot of individual samples (of participants who provided all four samples, n = 28) indicating changes in the relative abundance of most common genera over the course of AC-D treatment.
