Overview
The primary objective of this study is to show that the Supraglottic Index (SGI) is an easily-collected index that accurately identifies the presence and severity of laryngopharyngeal reflux (LPF) in idiopathic pulmonary fibrosis (IPF).
Description
The study team hypothesizes the SGI will correlate more strongly with measures of IPF severity (at baseline and over time) than gastroesophageal reflux (GER) data derived from the esophageal detector channels of a pH/impedance probe.
