  1. a The independent variables include third-trimester TyG index, maternal age, gestational weight gain, pre-pregnancy BMI, fetal gender, third-trimester HbA1c, GDM status, and HDP diagnosis.
  2. b The independent variables include third-trimester TyG index, maternal age, gestational weight gain, pre-pregnancy BMI, fetal gender, third-trimester HbA1c, and HDP diagnosis.
  3. c Lower and Upper indicate the spline-derived TyG index values in the third trimester at which the odds ratio for abnormal fetal growth equals 1. The numbers in parentheses represent the 95% confidence interval (CI) of the corresponding OR estimates.
  4. d p for non-linearity refers to the significance level of the non-linear association tested in the restricted cubic spline model.
