Insulin sensitivity has been compared between the two surgical procedures employing the Matsuda index or the M-value from a hyperinsulinemic euglycemic clamp in insulin-resistant individuals to assess peripheral insulin sensitivity and with the homeostatic model assessment (HOMA) in individuals with T2D to assess hepatic insulin sensitivity, yielding conflicting results [8, 10, 16, 17]. Here, INS is linked to type 2 diabetes mellitus.
