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:

Classroom intervention for illness-related problem behavior in children with developmental disabilities . There is growing evidence of an association between physical illness and problem behavior in children with developmental disabilities . Such behavior can compromise school performance . Therefore , the purpose of the present study was to evaluate , using a group design , the effectiveness of medical intervention alone ( N = 11 ) versus behavioral plus medical intervention ( N = 10 ) for illness-related problem behavior in a school setting . Following intervention , the behavioral plus medical intervention group showed lower levels of problem behavior and completed more academic tasks than did the medical intervention alone group . The results are discussed with respect to the concept of illness and pain as a setting event for problem behavior . The need for research to develop algorithms that allow one to select the best combination of medical and behavioral interventions for specific illnesses and contexts is noted .
