Sleeve Gastrectomy Surgery makes Obstructive Sleep Apnea Worse or Better?: a Multi-Center Observational Study in Patients with Obesity.
Observational study in Obesity surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
BACKGROUND AND
objectiveObstructive sleep apnea (OSA) is highly prevalent in the bariatric surgical population, with rates ranging from 50 to 70%. The impact of laparoscopic sleeve gastrectomy (LSG) on OSA and its associated risk factors remain relatively understudied. The aim of this study is to assess the effect of LSG on OSA and investigate predictors of new or worsening OSA postoperatively. Additionally, the study aims to provide evidence for the individualized selection of LSG procedures based on patient characteristics.
methodsThis multi-center observational study enrolled 119 patients with obesity who underwent LSG and were subdivided into two groups based on their preoperative AHI: AHI < 15 and AHI ≥ 15. The patients were followed up and evaluated before and 30 days after LSG. The study utilized univariate and multivariate analyses to assess risk factors for postoperative AHI development.
resultsFollowing LSG, there was a significant decrease in the mean AHI, leading to the resolution of OSA symptoms in 67.6% of patients with AHI ≥ 15. Neck circumference and the number of METS were also identified as independent risk factors for postoperative OSA. Furthermore, preoperative hypertension was found to be a significant predictor of new or worsened OSA after LSG.
conclusionLSG demonstrated effectiveness in improving OSA among patients with obesity. The study highlights the importance of preoperative hypertension evaluation and postoperative management in patients undergoing LSG. Further long-term, multicenter, and large-scale studies are recommended to validate and generalize these findings to diverse patient populations.
