  1. Data were analyzed by multivariable linear regression using Enter variables. (inclusion variables including Age; Education; Pre-pregnancy body mass index; Age at menarche; Parity; Abortion; TG; TC; LDL-c; HDL-c and Vitamin D concentrations)
  2. Abbreviation: TG Triglyceride, TC Total cholesterol, LDL-c Low density lipoprotein-cholesterol, HDL-c High density lipoprotein-cholesterol. Vitamin D concentration was stratified into Deficiency (< 20 ng/mL) group and Non-deficiency (≥20 ng/mL) group
  3. *Statistically significant P-value < 0.05
