Characteristics of upright versus supine reflux pattern in patients with laryngopharyngeal reflux.
Article in Brazilian journal of otorhinolaryngology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
introductionMany laryngeal-related problems have been attributed to laryngopharyngeal reflux including dysphonia, frequent throat clearing, chronic cough, and globus sensation. However, there is still controversy regarding diagnosis and clinical presentation of this disorder.
objectiveThe main objective of this study is to describe laryngopharyngeal reflux characteristics of different reflux position patterns in laryngopharyngeal reflux patients diagnosed with oropharyngeal pH monitoring.
methodsA retrospective chart review was conducted for 161 laryngopharyngeal reflux patients diagnosed with 24h oro-pharyngeal pH monitoring. Study subjects were categorized into upright and supine laryngopharyngeal reflux groups based on the pH results. The two groups were compared regarding the clinical presentation and pH characteristics.
resultsSignificant higher rates of upright laryngopharyngeal reflux position than supine laryngopharyngeal reflux position (P<0.0001) were reported among the study group. Reflux symptoms index results were significantly higher in the upright larybgopharyngeal reflux group compared to the supine laryngopharyngeal reflux group. 24h oropharyngeal pH measurements composite Ryan score was significantly higher in the upright group compared to the supine group (P<0.0001). No significant difference was found between the upright and supine laryngopharyngeal reflux groups regarding the frequency of clinical presentation or voice handicap index ratings.
conclusionLaryngopharyngeal reflux was found to be more prevalent occurring in the upright position among the study group. Reflux-related characteristics including pH parameters were more evident in the upright laryngopharyngeal reflux position.
