Development of positional obstructive sleep apnea (POSA) after upper airway surgery in OSA patients.
Article in Sleep & breathing = Schlaf & Atmung, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
purposePositional therapy (PT) has become more reliable for obstructive sleep apnea (OSA) patients with the use of new devices. The objectives of this study were to determine the preoperative prevalence of positional OSA (POSA) in our population of surgically treated patients and the proportion of patients who developed POSA after surgery and might improve with additional positional therapy.
methodsThis was a retrospective study of surgically treated OSA patients from 1999 to 2017. The Cartwright definition was used to define POSA. All patients completed a sleep study before and 6 months after surgery and a complete upper airway (UA) exploration (awake ± DISE). A total of 125 patients were included.
resultsThe global prevalence of POSA before surgery was 31.2%. In those who were cured by surgery, the preoperative prevalence of POSA was 38.3%. Having POSA was not related with surgical success outcome. For patients not cured by surgery, the proportion of POSA significantly increased from 25.64 to 53.85% after surgery. Eighteen patients of them (23.1%) achieved AHI < 5/h in a lateral position. In those patients, PT with Night-Shift™ was suggested, 50% of them accepted it and 88.9% of them experienced excellent satisfaction. Lateral velum collapse and the absence of concentric collapse at the tongue base had statistical relationships with the development of POSA.
conclusionsThe prevalence of POSA is increased after surgery in patients with persistent OSA after surgery. In these patients, the development of POSA gives an extra therapeutic chance as 23.1% of these cases can be successfully treated by using PT.
