Differentially abundant taxa of gut microbiota with the dynamic change in FBG level across the three trimesters. There were significant differences by linear discrimination analysis effect size (LEfSe) analysis between WNG and ENG groups in the first trimester (T1, A) and the third trimester (T3, B), between WNG and LNG groups in T1 (C) and T3 (D), between WNG and WHG groups in T1 (E) and T3 (F), between WHG and ENG groups in T1 (G) and T3 (H), between WHG and LNG groups in T1 (I). FBG: fasting blood glucose, WNG: normal FBG during the whole pregnancy, ENG: normal FBG in the early stage (T1) of pregnancy, LNG: normal FBG in the late stage (T3) of pregnancy, WHG: high FBG during the whole pregnancy
