MRX=Medicaid Rx, NSCAW=National Survey of Child and Adolescent Well-Being; nT=child-year observations.

Note: Utilization is the row mean and is non-exclusive; therefore, the sum may exceed the MRX or Red Book total. Expenditures reflect means for observations of children who are using a particular type of medication. Zeros are not included in the means.
