^aData are presented as least-square means and pooled SEM. Low-RFI FMT females, n = 8/time point; low-RFI FMT males, n = 7/time point; high-RFI FMT females, n = 7/time point; high-RFI FMT males, n = 6/time point; low-RFI CT females, n = 7/time point; low-RFI CT males, n = 7/time point; high-RFI CT females, n = 7/time point; high-RFI CT males, n = 7/time point. Sex affected Ruminococcaceae (P < 0.10).
