  1. *Intercept reflects change in HRQoL for age 80 women, and where covariates are set to zero: i.e., non-hip fracture, in home care, without comorbid conditions
  2. For example, the mean change in HRQoL for a group of men aged 85 years in LTC for hip fractures with heart/circulation conditions would be (−0.098) + (−0.002)  5 + (−0.011) + (−0.007) + (0.040) + (0.008) = − 0.078
