The data are presented as the mean ± SD.
BMI body mass index, SBP systolic blood pressure, DBP diastolic blood pressure, GWG gestational weight gain, GLU blood glucose, ALT alanine transaminase, AST glutamic oxaloacetic transaminase, UA uric acid, A/G albumin/globulin, PT prothrombin time, INR international normalized ratio, TBIL total bilirubin, TBA total bile acids, RBC red blood cells, WBC white blood cells.
aThe blood glucose levels were detected by a 75 g oral glucose tolerance test (OGTT) at the 23th–29th gestational week for the diagnosis of GDM.
