Bar Plot from Scientific Research

The top 10 bacterial biomarkers were identified by random forests regression of relative abundances of LEfSe-determined bacterial taxon against serum Kyn concentration. Statistical significance of selected bacterial biomarkers was assessed by permutation test (999 times). Data are represented as mean SD. In a and d, p-values were determined by independent samples t-test. NS not significant, * p-value 0.05, ** p-value 0.01, *** p-value 0.001. IncMSE increase in mean squared error
