Brown-Colored Malignant Pleural Fluid With High Bilirubin Levels: A Case Series.
Article in Case reports in pulmonology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Brown-colored pleural effusion is rare and may result from high bilirubin levels such as bilothorax (often described as a pleural fluid-to-serum bilirubin ratio of > 1.0). We describe four patients with malignant pleural effusion that appeared macroscopically brown with a pleural fluid-to-serum bilirubin ratio between 3.7 and 16.2. All had metastatic adenocarcinomas; three were from lung and one from gastric origin. None demonstrated clear pleurobiliary fistulas on investigations. Postulates for the development of brown effusion include heme oxygenase 1 overexpression in malignant cells situated in the pleura, intrapleural hemolysis, passive movement of bile through microscopic diaphragmatic pores, and drainage of biliary fluid into the pleural lymphatics.
