Multiple linear regression analysis using β cell function (DI₃₀ and DI₁₂₀) as the dependent variable

		β coefficient	SE	F‐value	p value
DI30 as dependent variable	Independent variable: mtDNA adjusted for age, sex, BMI, WC, HC, HOMA‐IR, lipid profiles and oxidative stress	0.104	0.011	5.56	0.019*
DI120 as dependent variable	Independent variable: mtDNA adjusted for age, sex, BMI, WC, HC, HOMA‐IR, lipid profiles and oxidative stress	0.116	0.013	6.923	0.009**

^* p < 0.05.

^** p < 0.01.

SE, standard error; DI, disposition index; mtDNA, mitochondrial DNA; BMI, body mass index; WC, waist circumference; HC, hip circumference; HOMA‐IR, homeostatic model assessment of insulin resistance.
