Even making "generous assumptions" about the likely 【C16】______ , the researchers found that a quarter of the proposed operations were 【C17】______ , since less invasive alternatives were available, 【C18】______ another third were as likely to harm the recipients as help them.
Parents needn’t 【C19】______ about ear tubes that are already in place. Once 【C20】______ implanted, the tiny devices provide drainage for six months to a year, then come out by reducing health costs by hundreds of millions of dollars every year.
