Patient selection for upper airway stimulation: is concentric collapse in sleep endoscopy predictable?
Article in Sleep & breathing = Schlaf & Atmung, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 23 papers, 1 of them a synthesis that pooled it.
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
purposeUpper airway stimulation is an effective treatment option for obstructive sleep apnea after failure of positive airway pressure (PAP) therapy. To ensure a therapeutic effect, closed-loop hypoglossal nerve implants require the absence of palatal complete concentric collapse during sleep endoscopy. The frequency and potential predictors of this exclusion criterion are unknown.
methodsOver a 2-year period, 74 consecutive patients with sleep apnea who sought PAP alternatives were evaluated with sleep endoscopy using propofol. The influence of sleep apnea severity and anthropometric characteristics as predictors of sleep endoscopy results was investigated.
resultsOne-fifth of all patients showed a concentric collapse. Gender and age did not predict the presence of concentric collapse, but higher body mass and apnea hypopnea index values were predictive (p = 0.011; e.g., 0.026). The most commonly used body mass index values for upper airway stimulation indications demonstrated acceptable specificity (BMI 32 kg/m(2) 0.71, 95 % confidence interval = 0.57, 0.82; e.g., 35 kg/m(2) 0.81, 95 % confidence interval = 0.69, 0.90). Despite the association with overweight, a significant number of severely overweight patients had no concentric palatal collapse.
conclusionsConcentric collapse is a somewhat common condition encountered in sleep endoscopy evaluations of PAP alternatives, and cannot be sustainably predicted with anthropometric or sleep assessments. Sleep surgeons should be aware of the possibility of concentric collapse, especially in candidates who are more overweight and have severe sleep apnea. Sleep endoscopy can be useful for providing information about continuous positive airway pressure (CPAP) alternatives or to motivate patient adherence to treatment.
