Bivariate box plot for the diagnosis of liver fibrosis and cirrhosis using gut microbiome-based ML (a); Deek’s funnel plot for the diagnosis of liver fibrosis and cirrhosis gut microbiome-based ML (b); Fagan diagram for the diagnosis of liver fibrosis and cirrhosis using gut microbiome-based ML (c). In figure (b), numerical circles represent the included prediction trials; the dotted line represents the regression line. In figure (c), the green rhombus represents the prior probability; the full red line represents the probability of the diagnosis of liver fibrosis and cirrhosis; the gray dotted line represents the probability of having liver fibrosis or cirrhosis
