Fig. 5: Network analysis showing the correlations between gut bacterial species and function.
From: Oral and gut dysbiosis leads to functional alterations in Parkinson’s disease

a, b Network analysis of the 20 selected species and associated functional pathways. The nodes between functions were eliminated and only the edges that have significant correlations are shown. The minimum R value cut-off was 0.35. The red color represents species or functions that were less prevalent in Parkinson’s disease (PD) patients, and the blue colors represent those that were more prevalent in PD patients.
