Management of a malpositioned central venous catheter in the accessory hemiazygos vein.
Article in BMJ case reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Malposition of a central venous catheter (CVC) in the accessory hemiazygos vein is an uncommon but potentially fatal complication; however, there is limited information regarding the preferred removal technique. We report a patient, a 57-year-old woman, who presented with overdose of her prescribed sedatives, who experienced this catheter complication after CVC insertion in the left internal jugular vein. The CVC was placed without resistance but routine postplacement chest X-ray showed abnormal coursing of the catheter close to the descending aorta. We used non-enhanced CT as an adjunct to safely identify the catheter position and assess for any bleeding during removal. CT images taken after retraction of the catheter tip by 10 cm showed no bleeding and we were able to remove the catheter safely. We recommend using CT as an adjunct to safely remove malpositioned catheters and reduce the risk of further complication.
