A systematic review and meta-analysis exploring the bidirectional association between asthma and gastroesophageal reflux disease in children.

Asthma is the most prevalent chronic respiratory disease in children, and gastroesophageal reflux disease (GERD) is one of its extraesophageal complications of asthma.
