INS and Insulin resistance: After adjusting for use of lipid lowering drugs, decreased GM MTR peak height was still significantly associated with higher indices of insulin resistance (fasted insulin (β = −0.411, p = 0.018), AUCinsulin(β = −0.415, p = 0.009), HOMA-IR (β = −0.436, p = 0.013), and insulinogenic index (β = −0.410, p = 0.012).
