OSAS and LPR also share obesity as an important risk factor. However, the relationship between LPR and OSAS remains unclear. This study aimed to correlate LPR as measured by the Reflux Symptom Index (RSI) and the Reflux Finding Score (RFS) with OSAS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This cross-sectional study included sixty-four subjects who underwent anamnesis to complete the RSI and the Epworth Sleeping Scale (ESS). The subjects were then divided into the OSAS and non-OSAS groups based on the Apnea-Hypopnea Index (AHI) obtained through a polysomnography examination. Both groups underwent a flexible fiberoptic nasopharyngolaryngoscopy examination to determine the RFS. LPR was identified based on the RSI and RFS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The mean BMI of the OSAS group significantly was higher than the non-OSAS group (\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u00a00.05). Most of the subjects in the OSAS group exhibited mild-moderate OSAS (AHI 10\u201329), and severe OSAS occurred in only seven subjects. The mean RSI and RFS values in the OSAS group did not differ significantly from the non-OSAS group (\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a00.34 and\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a00.36, respectively). The proportion of LPR between the mild-moderate OSAS group, the severe OSAS group, and the non-OSAS group did not differ significantly (\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a01.00).
