However, its relationship with OSA severity remains uncertain. Clarifying this association may improve reflux phenotyping and guide otolaryngology-focused evaluation in OSA populations.<\/jats:p>\n <\/jats:sec>\n \n Objective:<\/jats:title>\n To evaluate the association between LPR-related parameters and OSA severity and the relationship between velum obstruction grade and LPR-related measures.<\/jats:p>\n <\/jats:sec>\n \n Design:<\/jats:title>\n Prospective observational study.<\/jats:p>\n <\/jats:sec>\n \n Setting:<\/jats:title>\n Single tertiary academic medical center (Peking University Third Hospital), outpatient sleep clinic.<\/jats:p>\n <\/jats:sec>\n \n Participants:<\/jats:title>\n A total of 196 adults with polysomnography-diagnosed OSA were enrolled. All completed Reflux Symptom Index (RSI) assessment and laryngoscopic Reflux Finding Score (RFS) evaluation.<\/jats:p>\n <\/jats:sec>\n \n Intervention or Exposures:<\/jats:title>\n No intervention. Exposure was OSA severity classified by the apnea-hypopnea index and velum obstruction grade assessed by the M\u00fcller maneuver. Clinically defined LPR was operationally defined as RSI\u2009>\u200913 and\/or RFS\u2009>\u20097.<\/jats:p>\n <\/jats:sec>\n \n Main Outcome Measures:<\/jats:title>\n Associations between OSA severity, velum obstruction grade, and LPR-related measures.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n Clinically defined LPR was present in 84 of 196 patients with OSA (42.9%). RFS increased significantly with greater OSA severity (\n P<\/jats:italic>\n \u2009<\u2009.001), whereas RSI showed only a nonsignificant increasing trend (\n P<\/jats:italic>\n \u2009=\u2009.070). OSA severity correlated weakly with RSI and more clearly with RFS (\n r<\/jats:italic>\n \u2009=\u20090.16,\n P<\/jats:italic>\n \u2009=\u2009.023;\n r<\/jats:italic>\n \u2009=\u20090.33,\n P<\/jats:italic>\n \u2009<\u2009.001, respectively). After adjustment for sex, body mass index, and LSO\n 2<\/jats:sub>\n , moderate and severe OSA were independently associated with LPR compared with mild OSA (moderate: Odds ratio [OR]\u2009=\u20092.53; 95% Confidence interval [CI]: 1.08-5.95; severe: OR\u2009=\u20094.83; 95% CI: 1.59-14.66). Velum obstruction grade was associated with LPR prevalence and RFS.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n Clinically defined LPR was common in adults with OSA and was independently associated with greater OSA severity. RFS appeared to reflect OSA severity more consistently than symptom-based RSI, suggesting that laryngoscopic findings may better capture reflux-related laryngeal involvement in this population.<\/jats:p>\n <\/jats:sec>\n \n Relevance:<\/jats:title>\n Laryngoscopic assessment may complement symptom questionnaires and support phenotype-informed evaluation of reflux-related findings in OSA.<\/jats:p>\n <\/jats:sec>\n \n Level of evidence:<\/jats:title>\n 3<\/jats:p>\n
