Correlation analysis of FFAR2 mRNA level with age, history of diabetes, fasting blood glucose, and HDL-C level.

Group	N	Relative expression of FFAR2	Z	p value
Younger age	121	0.50 (0.06–1.51)
Older age	86	0.34 (0.03–1.02)	−1.552	0.121
Type 2 diabetes mellitus-free group	126	0.24 (0.02–1.13)
Type 2 diabetes mellitus group	38	0.26 (0.05–0.86)	−0.207	0.836
High fasting blood glucose group	71	0.39 (0.02–1.45)
Normal fasting blood glucose group	89	0.23 (0.02–1.08)	−0.956	0.339
Low HDL-C group	103	0.21 (0.02–1.02)
High HDL-C group	83	0.70 (0.15–1.79)	−3.508	0.000

HDL-C = high-density lipoprotein cholesterol.
