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:

Qigong massage treatment for sensory and self-regulation problems in young children with autism : a randomized controlled trial . Autism is commonly associated with sensory and self-regulatory disturbances . This article presents a randomized controlled study evaluating the effect of a 5-month intervention directed toward improving sensory impairment , digestion , and sleep in 46 children with autism < age 6 . The intervention , Qigong Sensory Training ( QST ) , is a qigong massage intervention based in Chinese medicine . It is two-pronged : Trainers work with children directly 20 times over 5 months , and parents give the massage daily to their children . Improvement was evaluated in two settings -- preschool and home -- by teachers ( blind to group ) and parents . Teacher evaluations showed that treated children had significant classroom improvement of social and language skills and reduction in autistic behavior compared with wait-list control participants . These findings were confirmed by parent data , indicating that the gains had generalized across contexts . A model and supporting data for understanding and treating sensory and self-regulation problems in autism is presented .
