Association between testosterone and ED in the multivariate regression analysis †.

†Multivariate adjusted for age, smoking status, alcoholic drinking, hypertriglyceridemia, hyperglycemia, elevated BP, low HDL-C and central obesity. Linear regression is conducted using the IIEF-5 score as a continuous variable, whereas the binary logistic regression is conducted using ED defined as a dichotomous variable using a cut-off point of IIEF-5

† 本研究针对年龄、吸烟状态、饮酒行为、高甘油三酯血症、高血糖、血压升高、高密度脂蛋白胆固醇（HDL-C）降低及中心性肥胖进行多变量校正。以国际勃起功能指数5（IIEF-5）评分为连续变量开展线性回归分析；以IIEF-5截点将勃起功能障碍（Erectile Dysfunction，ED）定义为二分类变量，进而开展二元logistic回归分析。
