Obstructive sleep apnea underdiagnosis: Prevalence and correlates from the Sleep Health and Knowledge in US Hispanics study.

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
Study Objectives: To examine the prevalence of obstructive sleep apnea (OSA) underdiagnosis and sociodemographic, behavioral, and medical correlates of underdiagnosis among Hispanic participants of Mexican descent and non-Hispanic white participants in San Diego, CA. Methods: Participants underwent overnight home polysomnography (PSG) and were eligible for the study if they met OSA diagnostic criteria at an apnea-hypopnea index (AHI) ≥ 15/h, minimum 3% oxygen desaturation. Participants self-reported their medical history including past OSA diagnosis, demographics, anthropometrics, and completed the Epworth Sleepiness Scale, and the Short Acculturation Scale for Hispanics. Logistic regressions were used to test bivariate and adjusted associations of correlates with OSA diagnosis status (diagnosed or undiagnosed). Results: Participants ( Conclusions: Most participants with moderate to severe OSA by home PSG were undiagnosed, regardless of their ethnicity. A lower AHI and no prior diagnosis of high blood pressure were associated with greater OSA underdiagnosis. Enhanced OSA screening, across groups, is needed to reach the large majority that are missed.
