^aCirculating vitamin E-based GRS, derived from three circulating vitamin E-SNPs; one-sample weighted and unweighted GRS, derived from dietary vitamin E-SNPs (P-value ≤ 5×10^-5)

^bAdjusted for sex, age, study centers, body mass index (BMI), smoking status, drinking status, and first ten principal components when appropriate

^cThe corrected P-value was calculated with false discovery rate (FDR) method
