Description: Volcano plots representing abundance differences (fold change) of different taxa between HC and PD patients at t = 0, t = 6, and t = 12 months. Statistically significant [–log(p) > 3; fold change > ± 1.3] compositional differences at the genus and family levels (represented by red dots) were apparent and indicative of a PD-related GM composition. Family taxonomic level, at the t = 6

Abundance in Group 1: increased abundance in Parkinson's disease (PD) patients at (t=6)
