Dependent variable: serum TG level at 42 days postpartum
Independent variables: serum TG level at each gestational week, baseline TG (TG of week 6–8), age, GWG, pre-BMI, GDM, and gestational age at delivery
If α ≤ 0.05, the variable was entered into the model, and the variable was ruled out if α ≥ 0.10
B unstandardized linear regression coefficient, β standardized linear regression coefficient
SE standard error, TG triglyceride, GWG gestational weight gain, Pre-BMI prepregnancy BMI, GDM gestational diabetes mellitus
