REM obstructive sleep apnea: prevalence and clinical associations in a high-altitude population.

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
objectivesRapid eye movement (REM)-associated obstructive sleep apnea (OSA) (REM OSA) has a prevalence of 17-74% of all OSA cases. At high altitude and in Latin America, there are no data on REM OSA and its relationship to daytime sleepiness and comorbidities. This study aimed to determine the prevalence of REM OSA and the differences in clinical and polysomnographic characteristics between OSA and REM OSA in a population living at 2,640 meters.
methodsA retrospective cross-sectional study was conducted on adults in Bogotá, Colombia between January and December 2022. Patients were considered to have REM OSA if they had a REM sleep duration of at least 30 minutes and the ratio of REM-apnea-hypopnea index to non-REM-apnea-hypopnea index was > 2, and non-REM-apnea-hypopnea index < 15. For comparing the OSA and OSA REM groups, the χ
resultsPatients with REM OSA and mild OSA had more severe nocturnal desaturation indices compared to mild non-REM OSA. Patients with OSA had a higher prevalence of arterial hypertension and ischemic heart disease.
conclusionsREM OSA prevalence in a population living at high altitude was low compared with other studies. The patients with REM OSA and mild OSA had more severe nocturnal desaturation indexes compared to REM OSA at sea level. This study suggests a possible subgroup of patients with mild OSA at high altitude who may benefit from a discussion about initiating continuous positive airway pressure therapy.
