Correlation between norepinephrine and Eubacterium, Parasutterella, Bacteroides abundance variations in HF group. In the HF group, after 5 weeks of dTMS treatment, a significant correlation was found between norepinephrine decrease and several genera variations: Eubacterium (r² = 0.734; p = 0.014), Parasutterella (r² = 0.618; p = 0.036), and Bacteroides (r² = 0.734; p = 0.014). Spearman correlation test and linear regression models were used for finding correlations and relationships among parameters.
