The lower IPA levels in feces correlate with more severe SALI. (A) The fecal IPA levels in patients (n = 15). (B) The receiver operating characteristic curves were used to identify SALI (n = 15). (C-E) The correlation analysis was performed between the level of IPA in stool and the level of ALT (C), AST (D), and bilirubin (E) on the day the patient was diagnosed with sepsis. IPA, Indole-3-propionic acid; SALI, sepsis-associated acute liver injury. The results are expressed as the mean ± SD, “*” indicates p < 0.05, “**” indicates p < 0.01, “***” indicates p < 0.001, p were determined by ANOVA and post-hoc test or by spearman analysis
