Our paper entitled “Limited agreement between current and long-term asthma control in children: the PACMAN cohort study” has been published in Pediatric Allergy and Immunology (2011: 22: 776–83). During further analysis of our dataset, we have noticed an error in one of the syntaxes we have used for the definition of long-term asthma control described in our paper. This mistake resulted in an overestimation of children in the uncontrolled group.

This shift from uncontrolled to partially controlled asthma does, however, not change our conclusions.

We apologize for any inconvenience caused.
