Differential microbial function analysis of the IC/BPS group and control group. A PICRUSt2 functional prediction analysis compared functional differences between the IC/BPS and control groups for differential microorganisms (Welch's t test, p < 0.05), with the Y-axis referring to a different function or pathway, the left half of the X-axis referring to the mean functional abundance, and the right half of the horizontal coordinates referring to the confidence interval range for the difference in functional abundance between groups. B Correlation analysis results of differential microorganisms with demographic characteristics and clinical symptoms (blue means negative correlation, red means positive correlation, *P < 0.05, **P < 0.01, ***P < 0.001)
