Table 3.
Results from the KMa analysis performed on data from 1 day to 1 year following fracture for the propensity-score-matched sex and age cohorts of patients with a hip fracture (individually or in combination: S72.0, S72.1, and S72.2) relative to the other fractures/fracture combinations specified within the table. Individuals deceased the same day as the fracture were not included in the patient cohorts. Only 1 hip fracture or other respective fracture-type event specified for each row was allowed from 60 to 89 years of age. Analyses performed on separated ICD-10b codes can be found in Table S4 of Multimedia Appendix 1.
