Bacterial composition of normal mucosa and AP tissues. A PCoA plot of unweighted Unifrac distances. R² and p values were calculated using ANOSIM (Analysis of Similarities). B Relative abundances of different phyla in normal mucosa (n = 32) and AP tissues(n = 28). C Relative abundances of different genera in normal mucosa and AP tissues. D LEfSe analysis. The only criterion for feature selection was log LDA score > 1.5. E Wilcoxon rank-sum test comparing the flora characteristics of normal mucosa and AP tissues. F Correlation between serum inflammatory factors and signature microbiota. *p < 0.05, **p < 0.01, and ***p < 0.001 (Spearman correlation test). C, normal mucosa; P, AP tissues
