Significant (p < 0.05) negative correlations were found between log10 ΔCFU/mL in the growth assays and protein, albumin and complement C3c levels in AF, and significant positive correlations between log10 ΔCFU/mL and serum bilirubin and aspartate aminotransferase (AST) levels (Table 1). Here, ALB is linked to atrial fibrillation.
