Iatrogenic superior vena cava syndrome with concomitant deep vein thrombosis of azygos and hemiazygos veins.
Article in Radiology case reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 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
Iatrogenic superior vena cava syndrome (SVCs) represents an emergent diagnostic entity and its correlation with deep vein thrombosis is extremely rare. Recently, the increased use of indwelling lines, pacemakers and intracardiac devices has led to more cases of SVC syndrome also associated with a higher frequency of DVT. We report an unusual complication in a 74-year-old female, who has been undergoing hemodialysis via CVC for 14 years, who referred at our Emergency Department complaining of shortness of breath, headache, face and neck swelling. She underwent chest Computed Tomography Angiography (CTA), that showed a thrombus extending from the superior vena cava to the azygos and hemiazygos veins. Acute SVCs should be suspected in emergency settings in symptomatic patients with indwelling central lines, catheters and pacemakers. CTA represents an accurate and quick imaging modality for the diagnosis and the assessment of the extension of the thrombus.
