Variations of gut microbiota composition in mothers of infants with CHD. Relative proportions of bacterial taxa at the phylum level (a) and genus level (b) were different between mothers of infants with CHD and controls. Only those bacterial phyla and genera with a relative abundance > 1% were presented independently, the others were merged and presented in “others”. (c) LDA score of thirty-four differentially abundant genera which were identified by LEfSe analysis and MaAsLin. CHD congenital heart disease, LDA line discriminant analysis, MaAsLin Multivariate Association with Linear Models algorithm.
