Dot Plot representation of significant differential species abundance in relation to disease severity metrics in PAH group. (a) Significant bacterial species by PVR > 5 Wood units. (b) Significant bacterial species by six‐minute walk distance. (c) Significant bacterial species by mPAP. *Bacterial species (Anaerostipes rhamnosivorans, Amedibacterium intestinale, Ruminococcus bicirculans, and Ruminococcus albus) significant across all three metrics of disease severity. FC, fold change; PAH, pulmonary arterial hypertension; PVR, pulmonary vascular resistance
