Men with treated hyperlipidemia were older, had more comorbidities, and used more medications compared with men with untreated hyperlipidemia or no hyperlipidemia. In multivariate models stratified by age and the presence of diabetes and/or cardiovascular disease (CVD), we saw no association between hyperlipidemia drug treatment and ED, except among younger men (<55) who had diabetes and/or CVD, where a strong association with an imprecise CI was observed (OR = 10.39, 95% CI: 3.25, 33.20)
