Prevalence and associated factors of obstructive sleep apnea in patients with pneumoconiosis: a cross-sectional study.
Article in BMC pulmonary medicine, 2026. 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
backgroundThis study aimed to assess the prevalence and clinical characteristics of obstructive sleep apnea (OSA) in pneumoconiosis patients using home sleep apnea tests (HSAT) and to identify associated risk factors.
methodsThis study is a single-center, cross-sectional investigation. Data collection encompassed clinical information, lung function, and arterial blood gas analysis. Additionally, patients completed questionnaires such as the STOP-BANG, Pittsburgh Sleep Quality Index (PSQI), Generalized Anxiety Disorder 7-item (GAD-7), and Patient Health Questionnaire-9 (PHQ-9).
resultsThe study enrolled 217 pneumoconiosis patients. Finding showed that 82% (179/217) had OSA: 37% (80) mild, 30% (65) moderate, and 15% (34) severe. Patients with moderate to severe OSA were significantly older than those with no or mild OSA groups (p = 0.005). Higher body mass index (BMI) was noted in patients with severe OSA compared to other groups (p < 0.001). Increased STOP-BANG scores were observed in moderate and severe OSA compared to no or mild OSA groups (p < 0.001). Additionally, arterial oxygen tension (PaO2) and arterial oxygen saturation (SaO2) levels were significantly higher in patients without OSA (p < 0.05). Logistic regression analysis identified older age, pottery pneumoconiosis, and a history of smoking as risk factors for OSA.
conclusionsOSA prevalence is high in pneumoconiosis patients. Targeted attention to OSA is beneficial, particularly for older patients, those with pottery pneumoconiosis, or former smokers.
