A review of the barium study of 507 children for the presence and severity of gastroesophageal reflux revealed 79 cases with coexisting pulmonary disease. Clinical-radiological analysis of the cases with respiratory disease showed good correlation between the radiographic demonstration of major reflux or no reflux and the presence or absence of pulmonary disease.
