Values of HbA1c, QUICKI and HOMA-IR in 13 patients with FM. All 13 patients with FM had at least one abnormal value pointing to IR (i.e., QUICKI, HOMA, or HbA1c). In this subgroup, there were 4 patients with HbA1c below 5.6%, but each of these 4 patients showed abnormal QUICKI and HOMA indices, consistent with IR. Conversely, 2 patients with normal QUICKI and HOMA values showed abnormal levels of HbA1c. G: Gender.
