  1. aAge thresholds are identified for each site of fracture, based on the graphical method, see Figure 2A. (70 years for hip, pelvis, others, multiple, proximal humerus (women), proximal tibia (women), vertebrae (men) and ribs (men) fractures; 75 years for proximal humerus (men), proximal tibia (men), distal femur (women), vertebrae (women), ribs (women) and skull (men) fractures; 80 years for skull fractures (women)).
  2. bThe correction factors are identified for each site of fracture, using the estimation of the sensitivity of high-energy codes for identifying non osteoporotic fractures. They are derived from the high-energy fracture/all fracture ratio from death certificates for ages 20 to 35 years, an age group in which all fractures are considered non osteoporotic. For example, when the sensitivity of high-energy codes is 80% at a site, the number of fractures is inflated by 20% (multiplied by 1.25).
  3. cCorrected number (rounded) = number of death certificates with high-energy (E-code) fractures above the age threshold * sex- and site-specific correction factor (1+(1-Sensitivity)).
  4. dOther fractures: fractures at other sites (shafts of long bones, forearm, ankle, bones of hand and foot) and unspecified body region.
