Bar chart labeled A shows the relative abundance of different bacterial genera in three samples, SC-1, SB-1, and SA-1, with a legend identifying each genus by color. Circular network diagram labeled B displays correlations among sixty-six microbial genera, with node size indicating abundance, edges colored for positive or negative correlations, and a legend showing genus names and the color scale for correlation values. — Metagenomic analysis results. (A) The top 10 genera in terms of abundance in HIF and correlation network diagram. (B) The circles represent species, and the size of the circles indicates the abundance; the thickness of the lines represents the strength of the correlation, and the color of the lines: red indicates a positive correlation, and green indicates a negative correlation.
