TNF and metabolic dysfunction-associated steatotic liver disease: We also observed that species that were decreased in CAD-NAFLD, such as uncultured bacterium clone 218002-1-48 (OTU17), Parasutterella excrementihominis (OTU61), and Bacteroides thetaiotaomicron (OTU26), were negatively correlated with inflammatory factors (e.g., IL-6, TNF-α, and IL-26).
