Central Venous Catheter-Related Extravasation Due to Delayed Vascular Erosion.
Article in Clinical case reports, 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
Central venous catheters (CVCs) are crucial in critical care but may occasionally lead to rare, serious complications such as vascular erosion and extravasation of infused solutions. Leakage of total parenteral nutrition (TPN) into the pleural space can mimic chylothorax, potentially delaying correct diagnosis and appropriate treatment. An 83-year-old male with COVID-19-related acute respiratory distress syndrome (ARDS) received TPN via a left-sided CVC, which remained in a suboptimal position for 18 days. On day 18, he developed sudden respiratory deterioration associated with bilateral milky pleural effusions. Initially misdiagnosed as chylothorax, subsequent pleural fluid analysis revealed elevated glucose and triglyceride levels. Computed tomography demonstrated vascular erosion near the junction of the brachiocephalic vein and superior vena cava. The CVC was subsequently removed, enteral nutrition initiated, and the pleural effusions resolved. However, the patient eventually succumbed to progressive ARDS. This case highlights the risk of delayed vascular erosion associated with suboptimally positioned CVCs, highlighting the diagnostic difficulty posed by TPN extravasation mimicking chylothorax. Prompt recognition of this complication is crucial to prevent adverse outcomes.
