The relationship of gastroesophageal reflux disease and asthma control.

Purpose: To study whether ACT responses are confounded by gastro-esophageal status (GERD), and if this is in concordance with the variation in Forced Expiratory Volume in 1 second (FEV1%) and Fractional Excretion of Nitric Oxide (FeNO).

Materials And Methods: This is a prospective cohort study ( = 307). Patients were surveyed for demographics data, and underwent ACT scoring, FEV1% and FeNO testing.
