Prevalence and characteristics of rapid eye movement-related sleep apnea in a population-based cohort.
Article in Annals of thoracic medicine. 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
backgroundThis study aimed to estimate the prevalence and characteristics of rapid eye movement-related obstructive sleep apnea (REMrOSA) in the general Saudi Arabian population, contributing novel data to the field and providing insights into this specific OSA phenotype.
methodsWe analyzed data from a previously described Saudi population study targeting school employees aged 30-60 years. The study was conducted in two stages: an initial screening of 2682 participants using screening questionnaires and a confirmatory test of 346 participants using polysomnography (PSG). OSA was defined as an apnea-hypopnea index (AHI) ≥5. REMrOSA was identified on the basis of specific criteria, including a REM-AHI/non-REM (NREM)-AHI ratio ≥2, NREM-AHI <15, and REM duration ≥30 min. An extrapolation method was used to estimate the prevalence of REMrOSA in the general population.
resultsAmong the 346 subjects who underwent PSG, 235 had OSA. Approximately one-third (30.64%) of these patients had REMrOSA, with a higher prevalence noted in females (38.03%) than in males (27.44%). The estimated prevalence of REMrOSA in the general Saudi population was 2.68%, with males (3.5%) being more affected than females (1.93%). Patients with REMrOSA presented lower AHI, Epworth Sleep Scale score, and arousal index than did those with non-REMrOSA (NREMrOSA). Logistic regression analysis indicated that patients with exclusive positional OSA (e-POSA) were 2.7 times more likely to have REMrOSA.
conclusionsREMrOSA is a common condition among patients with OSA, with an estimated prevalence of 2.68% in the general Saudi population. Patients with REMrOSA tend to have milder disease, are less symptomatic, and are seen more in e-POSA.
