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:

The Autism MEAL Plan : a parent-training curriculum to manage eating aversions and low intake among children with autism . Feeding problems represent a frequent concern reported by caregivers of children with autism spectrum disorders , and growing evidence suggests atypical patterns of intake may place this population at risk of nutritional and/or related medical issues , including chronic vitamin and mineral deficiencies , poor bone growth , and obesity . This combination of factors emphasizes a clear need to identify and disseminate evidence-based treatment of feeding problems associated with autism spectrum disorders . Behavioral intervention represents an effective treatment for chronic feeding concerns in this population ; however , evidence has largely been established with trained therapists working in highly structured settings . This pilot study seeks to fill this gap in the literature by describing and evaluating the Autism MEAL Plan , a behaviorally based parent-training curriculum to address feeding problems associated with autism spectrum disorders . We assessed the feasibility of the intervention in terms of program content and study protocol ( e.g . recruitment and retention of participants , assessment procedures ) , as well as efficacy in terms of changes in feeding behaviors . A total of 10 families participated in the treatment condition , and the program was evaluated using a waitlist control design ( n = 9 ) , representing the first randomized-control study of a feeding intervention in autism spectrum disorders . Results provide provisional support regarding the utility of the program , including high social validity , parent perception of effectiveness , and reduced levels of caregiver stress following intervention . Implications , limitations , and future directions for this line of research are discussed .
