Discussion Our analysis of 6155 patients (mean follow-up: 5.47 years) found that raloxifene showed a trend toward lower TKR risk vs. bisphosphonates in crude analysis (HR 0.62, 95% CI 0.42–0.93, p = 0.022), but this association became non-significant in the traditional adjusted Cox model (aHR 0.71, 95% CI 0.47–1.07, p = 0.102).
