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:

Feasibility and effects of nurse run clinics for patients with epilepsy in general practice : randomised controlled trial . Epilepsy Care Evaluation Group . OBJECTIVE To test the feasibility and effect of nurse run epilepsy clinics in primary care . DESIGN A randomised controlled trial of nurse run clinics versus " usual care . " SETTING Six general practices in the South Thames region . SUBJECTS 251 patients aged over 15 years who were taking anti-epileptic drugs or had a diagnosis of epilepsy and an attack in the past two years who met specified inclusion criteria and had responded to a questionnaire . MAIN OUTCOME MEASURES Questionnaire responses and recording of key variables extracted from the clinical records before and after the intervention . RESULTS 127 patients were randomised to a nurse run clinic , of whom 106 ( 83 % ) attended . The nurse wrote 28 letters to the general practitioners suggesting changes in epilepsy management . For this intervention group compared with the usual care group there was a highly significant improvement in the level of advice recorded as having been given on drug compliance , adverse drug effects , driving , alcohol intake , and self help groups . CONCLUSIONS Nurse run clinics for patients with epilepsy were feasible and well attended . Such clinics can significantly improve the level of advice and drug management recorded .
