  • In the binary regression analysis, the ED status (ED: IIEF-5 ≤21; non-ED: IIEF-5 >21) was treated as the dependent factor. Multivariate adjusted: age, BMI, WHR, smoke and drink. Binary HCY: normal HCY (5–15 µmol/L); hyperhomocysteinaemia (>15 µmol/L).

  • BMI, body mass index; B12, vitamin B12; ED, erectile dysfunction; FA, folic acid; HCY, homocysteine; IIEF-5, International Index of Erectile Function; WHR, waist:hip ratio.
