a
A taxonomical group was considered “signature” if it was detected in ≥25% of sites, comprised ≥1% (at the phylum or genus level) or 0.1% (at the OTU level) of the total microbiome of resolvers or pustule formers, and its relative abundance was significantly different (P < 0.05) between resolvers and pustule formers. Pre, preinfection; End, endpoint. *, trended towards significance.
b
The NB model fit the data better.
c
The ZINB model fit the data better.
