The results are given as the mean ± standard deviation. MO-L-IR: Morbid obesity with low insulin resistance; MO-H-IR: Morbid obesity with high insulin resistance; BMI: body mass index; HOMA-IR: homeostasis model assessment of insulin resistance index. Different letters indicate significant differences between the means of the different groups (P<0.05).
