Figure 6.

Bacterial species are more abundant in the PD than in the control group, according to the LefSE analysis. Features, as species, are described on the left side of the graphical output presented as bar plots. Red bar plots represent healthy controls and blue—PD patients. The presented features were selected based on the p-values < 0.05. (A) with bar plot represents the results of the study group with PD and other diseases (such as hypertension and diabetes), and (B) represents the results of the study group diagnosed only with PD, without other diseases.
