  1. OR Odds Ratio, 95 % CI 95 % Confidence Interval. BADL model: multivariate model considering status at six months (deteriorated or not) based on ability to perform basic activities of daily living (BADL) as assessed assessed through the Barthel Index; BADL was considered to have deteriorated if post-fall scores were <90 points or a pre-post score decrease of more than 10 % has occurrred. IADL model: multivariate model considering status at six months based on ability to perform instrumental activities of daily living (IADL) as assessed by the Lawton Scale; IADL was considered to have deteriorated when post-fall scores of <5 points were observed or a pre-post score decrease of 2 points occurred. Estimates presented: for age refer to 1-unit increases; and for baseline health-related quality of life (HRQoL) refer to 10-unit increases in the respective score scales. SF-12 PCS (SF-12 physical component summary); SF-12 MCS (SF-12 mental component summary); AUC (area under the curve)
