Dataset from Childhood Asthma Research and Education (CARE) Network Trial - Treating Children to Prevent Exacerbations of Asthma (TREXA)

Asthma is a common, serious illness among children in the United States. It can be effectively controlled through the use of preventative medications and "rescue" medications, which are used to control symptoms. This study will evaluate the impact and severity of asthma exacerbations that occur in children with mild persistent asthma who are receiving various combinations of medications for daily and rescue use.
