Characterization of obstructive sleep apnea in patients with insomnia across gender and age.
Article in Sleep & breathing = Schlaf & Atmung, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers, 1 of them a synthesis that pooled 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.
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
objectivesA large number of clinical observational studies have suggested that women patients with obstructive sleep apnea (OSA) have a higher presence of insomnia symptoms compared to men with OSA. There is no study that has examined the effect of age and gender on the relationship between OSA and chronic insomnia in a large number of patients with insomnia.
methodsWe collected data on 860 patients with chronic insomnia and included both sexes and a wide range of ages (mean age 43.0 ± 12.1 (range 18-81) years, 409 men). All participants underwent overnight polysomnography (PSG) in a sleep medicine center.
resultsThe prevalence of OSA based on three different apnea-hypopnea index (AHI) categories (events/h >5, >15, and >30) were 42.5, 21.8, and 8.3% in men and 19.1, 6.2, and 1.8% in women, respectively. Across age ranges of <35, 35~<45, 45~<55, and ≥55 years, the prevalence of OSA was remarkably greater in men than in women up to 55 years of age, but not in subjects with ages ≥55 years. AHI was a significant risk factor for hypertension; the odds ratio of hypertension in patients with high AHI (>30) compared to patients in the lowest AHI category (<5) was 3.68 (95% confidence interval [CI], 1.47-9.21), after adjusting for all other factors.
conclusionSimilar to the gender differences reported in general population studies, men had a much greater OSA prevalence than women prior to 55 years of age, but not at ages greater than 55 years.
