Does lung function change in the months after an asthma exacerbation in children?

Background: There are limited data describing lung function changes in children after an asthma exacerbation. Our hypothesis was that lung function does not fully recover in children in the months following an asthma exacerbation.

Methods: We used a data set of children with asthma where lung function (including FEV , FEV /FVC ratio and FEF ) was measured at 3-month intervals over a year.
