Jump Power Predicts Fracture Risk in Older Adults Independent of Sarcopenia and FRAX
Authors' conclusion
In summary, jump power predicted fracture risk in community-dwelling older adults independently of sarcopenia and FRAX MOF probabilities

Main finding
As reported in the abstract
Hazard ratio
2.16
P < 0.001
Fracture
Adjusted hazard ratio
1.45
P = 0.035
adjusted for FRAX major osteoporotic fracture (MOF) probability with bone mineral density (BMD) and Asian Working Group for Sarcopenia (AWGS) 2019 sarcopenia
Observational data: associations, not effects.
