Effects of sepsis and its treatment measures on intestinal flora structure in critical care patients

Figure 4 Key phylotypes showing significant differences among normal individuals, sepsis patients, and non-sepsis patients. A: Comparison of the fecal microbiota at the genus level among the three groups. The average abundance of each genus is depicted as the mean ± SE. P values were calculated using the Kruskal–Wallis rank-sum test: ^aP < 0.05; ^bP < 0.01, ^cP < 0.001; B: Heatmap representing the relative abundance of differential operational taxonomic units (OTUs) among the three groups. The key OTUs whose relative abundance was above 1%, as per random forest-based models are displayed in the “figure”.
