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
Chylothorax is an uncommon presentation of mediastinal lymphoma, typically attributed to direct tumour invasion. This case illustrates a rare mechanism of superior vena cava (SVC) thrombosis and venolymphatic hypertension, leading to refractory chylothorax. A 33-year-old man with primary mediastinal large B-cell lymphoma presented with dyspnoea and right-sided pleural effusion. He was diagnosed with chylothorax. Lymphangiography revealed lymphatic leak secondary to thrombosis involving the venolymphatic junction. Despite conservative management including repeated thoracentesis, talc pleurodesis, total parenteral nutrition and anticoagulation, the chyle leak persisted. Mechanical thrombectomy was performed, successfully restoring flow in the brachiocephalic veins and SVC. The chylothorax resolved completely afterwards, allowing the chest drain to be removed. This case highlights venous thrombosis as a possible cause of refractory chylothorax. When systemic anticoagulation fails, mechanical thrombectomy is a definitive, causality-driven treatment.
