  • In the multinomial logistic regression, the levels of HCY, B12 and FA were divided into quartiles (Q1<25%, 25%≤Q2≤50%, 50%<Q3≤75%, Q4>75%), which were treated as the categorical dependent variables. Q1 was the reference. As a binary categorical variable, the ED was put as the ‘Factors’. Multivariate adjusted: age, BMI, WHR, smoke and drink.

  • BMI, body mass index; B12, vitamin B12; ED, erectile dysfunction; FA, folic acid; HCY, homocysteine; WHR, waist:hip ratio.
