Definition: Compose a new way to ask the same question. The new question must be asking the exact same thing as the original question does. Without any other information, you should be able to tell that the original question and the new question are the same. Preserve bracketed phrases in your new question. You can change the rest of the question provided the above requirements are satisfied. The new question must have a natural, fluent formulation, as if it were composed by a native English speaker. You will be given three pieces of information to help you create better questions. Those are: "Answer": the answer to the question, e.g., "Honolulu". "Answer Type": the type of the answer, e.g., "Location". "Auxiliary Information" is a detailed description of some concepts mentioned in the question, if any.
Input: original question: How many cited works are there in the references of [A Phase I Evaluation of Azidothymidine (AZT) in Children with Acquired Immune Deficiency Syndrome (AIDS) or AIDS Related Complex (ARC)]?
answer: 4
answer type: Cited work.
auxiliary information: The study is designed to test the drug zidovudine (AZT) in children, including study of drug levels in various parts of the body fluids, safety of the drug, and its effect on different parts of the body. The effects of any drug, the way a drug enters the bloodstream, the way it is used by the body, and the way the body eliminates the drug may be very different in children compared with adults. The largest group of children who have AIDS are those who are less than 2 years of age. AIDS is often first identified in infants who are about 6 months old. Studies of AZT show that it might be useful in the treatment of AIDS. Thus it is important to study the effects of the drug in children.The effects of any drug, the way a drug enters the bloodstream, the way it is used by the body, and the way the body eliminates the drug may be very different in children compared with adults.

Patients are hospitalized for 8 weeks to receive AZT through the intravenous (IV) route at 1 of 2 doses. Patients are then discharged from hospital and take AZT by mouth for 4 more weeks.
