Bidirectional Mendelian Randomization Analysis for Vitamin D and Thyroid Peroxidase Antibody

Figure 1

(a) Association of the four vitamin D-related SNPs with 25 (OH) D (lnVD). (b) Association of the four vitamin D-related SNPs with TPOAb concentration (lnTPOAb). (c) Association of the four TPOAb-related SNPs with TPOAb concentration (lnTPOAb). (d) Association of the four TPOAb-related SNPs with 25 (OH) D (lnVD). Data were presented as unstandardized coefficients and 95% confidence interval. The model was adjusted for age, sex, and waist to hip ratio.
