Classification distribution of fecal microbiota in SONFH and AONFH patients. (A) Stacked bar chart illustrating the phylum-level bacterial proportions and composition in both groups. (B) Stacked bar chart depicting the genus-level bacterial proportions and composition in both groups. (C) At the genus level, grouped bar chart displaying the differentially abundant microbiota between SONFH and AONFH. (D) Radar chart depicting the distinct taxonomic compositions of the six significantly different genera. The inner green circle signifies a relative abundance of 0.0014211, the middle blue circle represents a relative abundance of 0.05, and the outer red circle represents a relative abundance of 0.12973.Gemmiger and Akkermansia are dominant in the steroid group, while Megamonas, Prevotella, and others are more abundant in the alcohol group. (E) Bar chart depicting the KEGG pathways that exhibit significant differences between SONFH (yellow) and AONFH (blue)(P<0.05)
