Difference in gut microbiota composition between PD patients and healthy individuals. A Branch plot showing the classification of species abundance of gut microbiota in PD patients (n = 31) and healthy individuals (n = 28). The circle radiating from inside to outside represents the classification level from phyla to genus, and the diameter represents the size of relative abundance. The yellow nodes indicate species without significant differences, the red nodes indicate species with higher abundance in healthy individuals, and the blue nodes indicate species with higher abundance in PD patients. B Histogram showing LDA distribution of species abundance of gut microbiota in PD patients (n = 31) and healthy individuals (n = 28)
