Co-occurrence networks illustrate bacterial interactions during Pre-COVID (A) and Post-COVID (B) periods, where nodes represent ASVs (size scaled to degree, colors denoting phylum affiliation), with red/blue edges indicating positive/negative correlations, respectively. Zi-Pi plot visualizations for Pre-COVID (C) and Post-COVID (D) periods reveal taxa interaction patterns. Network topology metrics (degree, betweenness, closeness, eigenvector centrality) alongside cohesion and average variation degree show statistically significant differences (Wilcoxon rank-sum test, *P < 0.05, **P < 0.01, ***P < 0.001) between periods (E).
