Correlation between Symptoms and Laryngeal Signs in Laryngopharyngeal Reflux

Objective/Hypothesis: Laryngopharyngeal reflux (LPR) is diagnosed by the presence of laryngeal signs and symptoms. Some studies have noted that signs and symptoms may be nonspecific and may have poor correlation. However, many such studies were either observational or had short‐term follow‐up. Therefore, we conducted subgroup analysis of a prospective concurrent controlled study with a 1 year follow‐up to study the correlation between signs and symptoms.
