Figure 1. Nonvertebral Fracture Rates Within 12 Months of Treatment Initiation by Disease Risk Score (DRS) Quintile and Drug Exposure.
Full cohort DRS: state-specific DRS equation created in the full cohort (covariates + exposures terms) and applied to all individuals based on individual covariate values (exposures excluded from equation)
Unexposed cohort DRS: state-specific DRS equations created among unexposed cohort (alendronate users) and then applied to all individuals based on individual covariate values
