Kaplan‒Meier survival probability analysis for SAR with a fragility fracture. At the end of the follow-up, the remaining participants at risk of being censored in each group who had not yet experienced a fragility fracture were as follows: low-level group (17%, n = 20), moderate-level group (12%, n = 14), and high-level group (7%, n = 8) (log-rank test, P < 0.0001), suggesting that the survival probability from a fragility fracture decreases with increasing SAR levels
