osteocalcin	0.618	0.449–0.850	0.003	0.979	0.693–1.383	0.905	0.936	0.655–1.339	0.718

*In the linear regression analysis, as a continuous variable the IIEF-5 score is treated as the dependent factor. In the binary logistic regression analysis, ED (dichotomous variable: ED or without ED) is treated as the dependent factor.

*ED: erectile dysfunction; BMI: body mass index; WHR: waist hip rate; OR: odd ratio; 95%CI: 95% confidence interval.

*Multi-adjusted: age, BMI, WHR, smoke and drink.
