a At the phylum level, the number of Firmicutes was significantly reduced in the gallstone group, and the Firmicutes/Bacteroidetes (F/B) ratio was also significantly decreased. Cyanobacteria, Fusobacteria, and Spirochaetes were significantly increased in the gallstone group. b The structure and relative abundance of the flora in the two groups at the class, order, family, genus, and species levels. c At the genus level, the gallstone and control groups were compared, and the bacteria with significantly increased abundance are shown. d The bacteria with significantly reduced abundance are shown. Data are expressed as the mean ± SD, *p < 0.05, **p < 0.01, ***p < 0.001, ns > 0.05. Statistically significant differences (p < 0.05) between the two groups were determined by Mann-Whitney U test
