Screening for obstructive sleep apnea before coronary angiography.
Article in The clinical respiratory journal, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
introductionThe prevalence of obstructive sleep apnea (OSA) in patients with suspected coronary heart disease (CHD) is yet to be clarified. This study aimed to investigate the prevalence of OSA before coronary angiography (CAG).
methodsWe retrospectively evaluated patients with suspected CHD admitted to the Department of Geriatric Cardiology of our hospital between July 2019 and July 2021. OSA was screened using the level III home sleep apnea test before CAG. The prevalence of OSA was then compared between the CHD and non-CHD groups. CHD severity was determined using the Gensini score of CAG results, and OSA severity was graded using the apnea-hypopnea index (AHI).
resultsAmong the 327 patients, 211 had CHD. In total, 264 patients were diagnosed with OSA (80.7%) (184 patients, CHD group [87.2%]; 80 patients, non-CHD group [69.0%]). The CHD group had a significantly higher prevalence of OSA (P < 0.01) and higher AHI (CHD group 18.76 ± 14.94, non-CHD group 11.56 ± 10.67, P < 0.01). The Gensini score was positively correlated with OSA severity in patients with CHD, and AHI ≥ 20 was a risk factor for CHD (odds ratio: 1.961, 95% confidence interval: 1.065-3.608, P < 0.05).
conclusionOSA screening before CAG revealed a higher prevalence in CHD patients than in non-CHD patients. The degree of coronary artery obstruction is positively correlated with AHI, and AHI ≥ 20 is a risk factor for CHD. Therefore, attention should be paid to OSA screening and management before CAG in patients with suspected CHD.
