Maternal insulin level and HOMA-IR index at different time points in different groups. Data were expressed as median with whiskers as inter-quartile range. Women in the Ch-R group received 400 ml oral carbohydrate-rich solution 2 hours before the surgery. Women in the placebo group took 400 ml clear water 2 hours before the surgery. Women in the fasting group received preoperative fasting. Biochemical indices before intervention were measured at 2 hours before the surgery (before preoperative carbohydrate-rich solution or water was taken), while indices immediately after and 1-day after the surgery were obtained when they returned to the ward from the surgery room immediately and 6:00 AM on the day after the surgery day, respectively. A Maternal insulin levels at different time points in different groups; B Maternal HOMA-IR index at different time points in different groups. CD, caesarean delivery; HOMA-IR, homeostatic model assessment of insulin resistance
