Abbreviations: CI = confidence interval; MrOS = The Osteoporotic Fractures in Men Study; OR = odds ratio; RI = rhythmic index. Model I: adjusted for age and site.
Model II: additionally adjusted for race, education, smoking status, and alcohol use.
a
N and % were calculated based on participants in each quartile of the RI and OR and 95% CI were calculated as per 0.1 increase in RI.
