CRP and Ascites: In the Cir group, serum tryptamine levels showed a negative correlation with the presence of ascites (r = − 0.546, p = 0.002), NEUT% (r = − 0.518, p = 0.003), and CRP levels (r = − 0.531, p = 0.003); serum AA levels were positively correlated with WBC (r = 0.528, p = 0.003); and a negative correlation was observed between faecal acetic acid and CRP levels (r = − 0.551, p = 0.002).
