Association of overlap syndrome with incident atrial fibrillation.
Article in Internal and emergency medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Increasingly compelling data link chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) to cardiovascular complications independent of known comorbidities. It remains unclear whether the association is amplified in the presence of both conditions. The aims of this study are to assess the prevalence of atrial fibrillation (AF) in overlap syndrome (OS) and to identify risk factors predisposing to this atrial arrhythmia. We conducted a retrospective cohort study of 268 adults without past or current AF who were referred for an initial diagnostic polysomnogram from 2012 to 2019. A logistic regression analysis was performed to identify risk factors for incident AF. Incident AF occurred in 64 subjects [cumulative probability 24%, 95% confidence interval (CI) 19-29]. Independent predictors of incident AF were age-adjusted Charlson index [Odds ratio (OR) 1.62; 95% confidence interval (CI) 1.3-2.0], percentage of time spent with O
