Data are presented as least-square means and pooled SEM. Low-RFI FMT females, n = 8; low-RFI FMT males, n = 7; high-RFI FMT females, n = 7; high-RFI FMT males, n = 6; low-RFI CT females, n = 7; low-RFI CT males, n = 7; high-RFI CT females, n = 7; high-RFI CT males, n = 7. Different lowercase superscript letters within a row indicate a significant difference (P≤ 0.05); different uppercase superscript letters within a row indicate a tendency (P ≤ 0.10).
