You will be shown an abstract from a biomedical research paper. Given this abstract, your task is to extract all unique entities of the following types: ["Outcome", "Participant", "Intervention"].

Please return the output as a JSON object of the format: {"Participant" : ["patients with COPD", ...], "Intervention" : ["Atenolol", ...], "Outcome" : ["blood pressure", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

Most functional outcomes are similar for men and women after hip fracture : a secondary analysis of the enhancing mobility after hip fracture trial . BACKGROUND The impact of gender on functional outcomes after hip fracture is not known . We aimed to determine the extent to which gender influenced functional outcome and response to exercise in older people after hip fracture , and to determine if any differences persisted after adjusting for cognition , weight and age . METHOD Secondary analysis of data from the Enhancing Mobility After Hip Fracture trial in which older people after hip fracture received either a lower or higher intensity exercise program . Functional outcomes included physical performance and self-reported measures . Regression models were used to compare genders at baseline , week 4 and week 16 , with adjustment for baseline values , cognition , weight and age . Interaction terms were used to assess a differential impact of the intervention by gender . RESULTS Outcome data were available for 160 participants , 30 men ( 19 % ) and 130 women ( 81 % ) at baseline , with the withdrawal of 4 men ( 13 % ) and 6 women ( 5 % ) at week 16 . There were no gender differences for any baseline measures or for most of the 19 functional outcome measures at weeks 4 and 16 . At week 4 men performed better in knee extensor strength ( 2.1 kg , 95 % CI 0.6 to 3.7 , p < 0.01 ) . This difference did not persist after adjustment for body weight , however persisted after adjusting for baseline , cognition , and age ( p = 0.038 ) . At week 4 , men performed better in coordinated stability ( -10.0 error score , 95 % CI -17.6 to -2.4 , p=0.010 ) and this persisted after adjusting for baseline values only but not for cognition and age ( p = 0.073 ) . At week 16 , men performed better in coordinated stability ( -10.2 error score , 95 % CI -18.4 to -1.9 , p=0.016 ) and this persisted after adjusting only for cognitive impairment ( p = 0.029 ) but not for age and baseline ( p = 0.135 ) . There was no indication of a differential impact of intervention type on the basis of gender . CONCLUSIONS A few between gender differences were observed in strength and balance , however these appeared to be confounded by body weight , age and/or cognition .
