Bariatric surgery and obstructive sleep apnea: a systematic review and meta-analysis.

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
backgroundSeveral studies evaluated the effect of bariatric surgery on obstructive sleep apnea (OSA) but findings have been inconsistent. The aim of this study was to conduct an updated systematic review and meta-analysis to investigate the effect of bariatric surgery on OSA.
methodsThe databases for PubMed, CENTRAL, and Scopus were searched up to the 1st of December, 2021. Studies were included if they were cohort or case-control in design, included patients with diagnosis of OSA, the patients underwent any bariatric surgery, and the study performed postoperative polysomnography.
resultsThe total number of the included patients was 2310 patients with OSA from 32 studies. Our analysis showed that bariatric surgery was associated with significant reduction in BMI (WMD = - 11.9, 95%CI: - 13.4, - 10.4), apnea-hypopnea index (AHI) (WMD = - 19.3, 95%CI: - 23.9, - 14.6), and respiratory disturbance index (RDI) (WMD = - 33.9, 95%CI: - 42.1, - 25.7). The rate of OSA remission after the surgery was 65% (95%CI: 0.54, 0.76).
conclusionOur results suggest that bariatric surgeries are effective in reducing obesity among patients with OSA in addition to OSA severity measures. However, the low rate of OSA remission suggests that the main etiology of OSA is not only obesity but also includes other important variables such as the anatomy of the jaw.
