Composition variation was also found among the HA subgroups (HA-1, HA-2, and HA-3), which was also not significant (all p > 0.05), with exceptions for Bacteroides uniformis and Mediterraneibacter gravus , which were borderline significant between HA-2 and HA-3 and between AD and HA-3 (both p = 0.05), respectively ( Figure 1 and Figure 2 ).
