Comparison of G1, G2, and G3 of HOMA-IR and glucose metabolism indices (FINS, HbA1c).

	G1	G2	G3	value	value	value
HOMA-IR	6.44 ± 1.70	5.00 ± 1.94	4.80 ± 2.57	0.006	0.204	0.000
FINS (μU/mL)	141.20 ± 72.59	128.14 ± 56.79	93.23 ± 65.82	0.590	0.010	0.001
HbA1c (%)	10.08 ± 2.78	7.87 ± 2.34	9.99 ± 2.89	0.000	0.003	0.955
