a
To convert 25(OH)D levels to nmol/L from ng/ml, multiply by 2.496.
b
p for interaction
c
The prevalence of ED by race/ethnicity is as follows: 15.1% in Non-Hispanic Whites, 15.1% in Non-Hispanic Blacks, 17.1% in Mexicans/Hispanics, and 12.8% in other races.
d
Model is adjusted for age, smoking, alcohol consumption, BMI, physical activity, hypertension, diabetes, hypercholesterolemia, eGFR, CRP, and the use of antidepressants and beta-blockers.
National Health and Nutrition Examination Survey = NHANES; Erectile Dysfunction = ED; 25-hydroxyvitamin D = 25(OH)D; Body Mass Index = BMI; C-Reactive Protein = CRP; Estimated Glomerular Filtration Rate = eGFR
