Differentially abundant taxa of gut microbiota in all the subjects across the three trimesters of pregnancy. There were significant differences in the abundance taxa of gut microbiota (GM) by linear discrimination analysis effect size (LEfSe) analysis [linear discrimination analysis (LDA) score > 2.0] between the first trimester (T1) and the second trimester (T2) (A), and between T1 and the third trimester (T3) (B)
