Fig. 4: Dynamic changes in microorganism abundances.

A, B Depiction of the relationships between the abundances of Ec and Sa and among Bv, Ec, and Sa, respectively. The dashed line represents the 90% abundance threshold of each microorganism in the control group. Notably, the statistical sample excludes 0 values. The x axis illustrates robust linear fitting across specimens with varying abundance intervals. The blue and red notations represent the normal and overgrowth states, respectively. C Relationships between changes in the abundances of Bv and three other pathogenic bacteria observed across the six patients in Group 3.
