When compared to the non-hyperhomocysteinemia group (tHcy ≤ 15 μmol/L), diastolic BP, the prevalence of ICP, PE, and PTB, platelet count, the levels of TBA, direct bilirubin, urea nitrogen, creatinine, and LDL-C, were significantly higher in the hyperhomocysteinemia group, whereas age, BMI, assisted reproduction rate, GDM prevalence, fetal birth length and weight, RBC count, the levels of vitamin B12, folic acid, hs-CRP, ALT, and HDL-C were significantly lower in the hyperhomocysteinemia group (Table 2). Here, GPT is linked to hyperhomocysteinemia.
