Questionnaire and polysomnographic evaluation of obstructive sleep apnea in a cohort of post-COVID-19 patients.
Observational study in Medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
To evaluate the efficiency of 5 screening questionnaires for obstructive sleep apnea (OSA), OSA frequency, and the association between OSA and COVID-19 severity in recent COVID-19 cases, and to compare the use of the oxygen desaturation index (ODI) as an alternative measure for the respiratory disturbance index (RDI). This open cohort study recruited patients with recent COVID-19 (within 30-180 days) diagnosed using reverse transcription polymerase chain reaction. Participants were screened for OSA using the following 5 sleep disorder questionnaires prior to undergoing type I polysomnography: the Sleep Apnea Clinical Score (SACS), Epworth Sleepiness Scale (ESS), STOP-Bang score, No-Apnea score, and Berlin questionnaire. Polysomnography revealed that 77.5% of the participants had OSA and that these patients exhibited higher COVID-19-related hospitalization (58%) than those exhibited by non-apneic patients. The Kappa coefficient showed reasonable agreement between RDI > 5/h and No-Apnea score, RDI > 15/h and Berlin questionnaire score, and Epworth Sleepiness Scale and STOP-Bang score, but only moderate agreement between RDI > 15/h and No-Apnea score. An OSA-positive No-Apnea score increased the specificity of the SACS to 100% when RDI > 5/h. The intraclass correlation coefficient showed 95.2% agreement between RDI > 5/h and ODI > 10/h. The sequential application of the No-Apnea score and SACS was the most efficient screening method for OSA, which had a moderately high incidence among the post-COVID-19 group. We demonstrated an association between OSA and COVID-19 related hospitalization and that ODI could be a simple method with good performance for diagnosing OSA in this population.
