Data are expressed as mean + SEM (%).

^aP < 0.05 vs control. Bacterial species whose relative abundance was < 1% in both the control and transaction surgery group are compiled within the “other” category. Significant changes in bacteria whose relative abundance was < 1% are detailed within the text.
