Quality-of-life outcomes before and after multilevel pharyngeal surgery in moderate-to-severe obstructive sleep apnea.
Article in Brazilian journal of otorhinolaryngology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesTo assess changes in subjective quality of life (dizziness, tinnitus, sleep quality, daytime sleepiness) in moderate-to-severe obstructive sleep apnea patients before and after multilevel pharyngeal surgery (uvulopalatopharyngoplasty, bilateral tonsillectomy and tongue-base radiofrequency ablation), and identify the main factors influencing postoperative outcomes.
methodsThirty-one OSA patients diagnosed via Polysomnography (PSG) underwent preoperative bilateral bithermal caloric testing and completed the Dizziness Handicap Inventory (DHI), Tinnitus Handicap Inventory (THI), Pittsburgh Sleep Quality Index (PSQI), and Epworth Sleepiness Scale (ESS). Assessments were repeated 6-months postoperatively. Pairedt-tests compared pre/post scores, and multiple linear regression identified factors affecting quality of life.
resultsOur analysis revealed three major findings: (1) Canal Paresis (CP) was not correlated with DHI scores; (2) Postoperative DHI, THI, PSQI, and ESS scores significantly decreased (p ≤ 0.05). The 95% confidence intervals for the differences were 2.396-8.830, 0.773-3.356, 2.835-4.907, and 3.376-7.140, respectively; (3) Apnea-Hypopnea Index (AHI) and Lowest Oxygen Saturation (LSpO
conclusionsThe subjective quality of life in moderate to severe OSA patients, particularly for dizziness, tinnitus, sleep quality, and daytime sleepiness, was significantly improved after surgical treatment. In terms of postoperative quality of life, AHI and LSpO LEVEL OF EVIDENCE: 2:
