1 · What the graph read from 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.

2 · The registry

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

objectivesTo address a gap in the literature on the prevalence and predictors of obstructive sleep apnea (OSA) among patients undergoing bariatric surgery in Saudi Arabia, considering the region's unique cultural and dietary practices.

methodsThis retrospective study at King Saud University Medical City, Riyadh, analyzed data from morbidly obese patients referred from the bariatric surgery unit to the sleep disorders clinic. Using the Sleep Disorders Center database (September 2015 to March 2019), it examined demographic and clinical variables, with in-laboratory polysomnography (PSG) employed to diagnose and assess OSA severity.

resultsThe study assessed 265 morbidly obese patients for OSA using PSG before bariatric surgery. Of these, 153 (57.7%) were diagnosed with OSA, with the mean apnea hypopnea index for patients with OSA being 67.8±19.6 events/hr. In terms of predictors, our study identified age, body mass index, neck circumference, male gender, smoking, snoring, ankle swelling, hypertension, and diabetes mellitus as significant factors associated with OSA. Additionally, our study found that waist measurements, hemoglobin level, and hematocrit were significant predictors.

conclusionThis study underscores the high prevalence of OSA in bariatric surgery patients in Saudi Arabia and delineates several demographic and clinical factors associated with the condition. These findings highlight the importance of screening for OSA in this population to optimize patient outcomes and minimize postoperative complications.
