Carrillo-Larco RM, et al. - Researchers performed a population-based cross-sectional study to evaluate the diagnostic accuracy of four undiagnosed type 2 diabetes mellitus risk scores accounting for erectile dysfunction status. The findings from the present study suggested that erectile dysfunction was more common in men with type 2 diabetes than in otherwise healthy men. The accuracy of well-known risk scores for undiagnosed type 2 diabetes could be improved by screening for erectile dysfunction before screening for type 2 diabetes.
