Comparison of upper airway collapse patterns and its clinical significance: drug-induced sleep endoscopy in patients without obstructive sleep apnea, positional and non-positional obstructive sleep apnea.

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
purposeTo compare patient characteristics, upper airway (UA) collapse patterns and treatment outcome in obstructive sleep apnea (OSA) patients, including non-positional OSA patients (NPP) and positional OSA patients (PP), and non-OSA.
methodsCohort study of patients screened for OSA in 2012. Polysomnography was performed and UA was evaluated using the VOTE classification during drug-induced sleep endoscopy (DISE). Treatment outcome of MAD and UA surgery was evaluated.
resultsEight hundred sixty patients were included. Higher BMI, larger neck circumference, and greater age were independent significant predictors for OSA. DISE was performed in 543 patients: 119 non-OSA and 424 OSA patients of whom 257 PP and 167 NPP patients. PP were younger, had smaller neck circumference, lower BMI and apnea-hypopnea index (AHI) than NPP. Collapse at velum (p < 0.001) and oropharynx (p < 0.001) significantly increased the odds for having OSA. Tongue base and epiglottis collapse were, on group level, not determinative for OSA or non-OSA. Complete concentric collapse (CCC) was observed less frequently in PP (31.5%) as compared to NPP (46.1%). After UA surgery, OSA often was cured or improved to less severe positional OSA. Lower efficacy of UA surgery was observed in PP as compared to NPP. No differences were observed in MAD treatment outcome.
conclusionsCurrent study provides insight in patients screened for OSA: collapse at velum and oropharynx significantly determined presence of OSA and CCC occurred less frequently in PP compared to NPP. In addition, residual positional dependency is common after UA surgery. More trials are needed to gain insight in pathophysiology and treatment outcome.
