After adjusting for the risk factors (age, sex, BMI, WC, HDL, TG, diabetes mellitus, and hypertension) (Table S5), the association of PNPLA3 rs738409 C>G, F2 was positively correlated with the GG genotype (OR = 5.482, 95%CI 1.572–19.112, p = 0.008), F3 was positively correlated with the GG genotype (OR = 9.641, 95%CI 1.493–62.233, p = 0.017), F4 was positively correlated with the GG genotype (OR = 107.296, 95%CI 1.411–8157.152, p = 0.034), F2-F3-F4 did not show statistical significance with the CG genotype. Here, PNPLA3 is linked to diabetes mellitus.
