APOB and gestational diabetes: As exhibited in Table 3, the subgroup analysis of women with GDM showed that the low-LDL-C subgroup exhibited higher pre-pregnancy BMI, OGTT-fasting glucose levels, and TG/HDL-C ratios but lower apoA1, HDL-C, apoB, TC, non-HDL-C, AI, apoB/apoA1 ratios, and MDA levels than the high- and medium-LDL-C subgroups (P < 0.05), was inclined to have decreased OSI than the medium-LDL-C subgroup (P = 0.057), and had higher delivery BMI (P = 0.005) and tended to have increased TG levels (P = 0.082) than the high-LDL-C subgroup.
