You will be shown inclusion or exclusion criteria for a clinical trial. Given these criteria, your task is to extract all unique entities of the following types: ["Observation", "Condition", "Procedure", "Drug", "Temporal", "Multiplier", "Qualifier", "Negation", "ReferencePoint", "Scope", "Value", "Mood", "Device", "Visit", "Measurement", "Person"].

Please return the output as a JSON object of the format: {"Condition" : ["breast cancer", ...], "Device" : ["ports", ...], "Drug" : ["Atenolol", ...], "Measurement" : ["blood pressure", ...], "Mood" : ["suspected", ...], "Multiplier" : ["more than two", ...], "Negation" : ["no", ...], "Observation" : ["history", ...], "Person" : ["male", ...], "Procedure" : ["surgery", ...], "Qualifier" : ["severe", ...], "ReferencePoint" : ["enrollment", ...], "Scope" : ["infection", ...], "Temporal" : ["one day", ...], "Value" : ["50%", ...], "Visit" : ["ICU", ...]}. 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:

1. Age: 12 to 36 months of age (The diagnosis of CP is often uncertain under the age of 12 months. The cutoff at 36 months is to have a population of young children when the brain is most "plastic" and most susceptible to reorganization). 
2. Diagnosis: Diagnosis of spastic CP confirmed by a pediatric neurologist or pediatric rehabilitation specialist. 
3. Etiology: The insult to the central nervous system that caused the motor dysfunction must have occurred during gestation or within one year after birth independent of gestational age. 
4. Disease severity level: Gross Motor Function Classification System (GMFCS) levels I, II and III.
