Associations among Self-Reported Laryngopharyngeal Reflux, Allergic Symptoms, and Type of Dysphonia.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Dysphonia is defined as a change in voice timber, pitch, or loudness. Precipitating factors may be occupational or health-related, such as allergy and laryngopharyngeal reflux (LPR). Objective: To investigate the association between combined LPR, and allergic rhinitis (AR), and type of dysphonia, that is, functional versus non-functional. Methods: A retrospective chart review of all patients with dysphonia who presented to the Voice Unit at a tertiary referral center between November 2018 and February 2022 was conducted. Patients must have previously filled out the Reflux Symptom Index (RSI) and AR questionnaires to be recruited. Based on laryngeal examination, the etiology of dysphonia was stratified as functional versus non-functional (referred to as structural/neurologic). Results: A total of 137 patients were included, 65 (47.4%) of whom had a structural voice disorder, 22 (16.1%) had neurologic voice disorders, and 50 (36.5%) had a functional voice disorder. Seventy-eight patients (56.1%) had a positive RSI ≥ 13, suggestive of LPR. In these patients, dysphonia was functional in 31, structural-in 34, and neurologic in 13 ( Conclusion: Patients with dysphonia and history of LPR and allergy are more likely to have a functional underlying etiology.
