Furthermore, from the 18 studies, 11 [27,55,57,59,60,61,62,64,65,68,70] showed a significant difference (p ≤ 0.05) between patients with DM1 and controls (Table S1); namely, higher levels of insulin [57,59,61,62], HOMA-IR [27,57,61,65,70], total cholesterol [55,57,60,65], LDL [60,68], TAG [27,57,59,60,65,68], whereas glucose levels [64] and HDL were significantly lower [59,60,65]. Here, INS is linked to myotonic dystrophy type 1.
