†OR (95% CI).
‡Reference value for all comparisons using ORs are 1.00; each variable is compared against all other remaining variables within category. For example, within ‘Activity Factors’, odds for facture during falls while ‘reaching in standing’ are expressed as a ratio against odds for fracture after falls related to all other activity variables. Hospital and residential care results are presented in parallel but have been analysed separately.
