Case Report: Necrotizing pulmonary destruction and fatal gangrene: the imperative of early recognition.
Article in Frontiers in medicine, 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
Introduction: Pulmonary gangrene is a catastrophic end-stage manifestation of necrotizing pulmonary infection, often arising on the basis of unrecognized and chronically survived pulmonary thromboembolism. Large-vessel thrombosis leads to ischemia and infarction of pulmonary parenchyma, creating an ideal substrate for secondary infection with subsequent rapid tissue devitalization. Impaired perfusion prevents adequate antibiotic delivery, facilitating explosive progression of necrosis. Case description: We report a fatal case of pulmonary gangrene in a 59-year-old man with a history of chronic alcohol abuse and prior gastric resection due to ulcer disease. Initial imaging demonstrated bilateral cavitations, while clinical deterioration despite broad-spectrum antimicrobial therapy revealed complete destruction of the left lower lobe, hydropneumothorax, and pulmonary embolism. Autopsy confirmed pulmonary gangrene, pulmonary infarction, and bilateral pyothorax. Conclusion: This case highlights the importance of recognizing pulmonary infarction secondary to thromboembolism as a fertile ground for fulminant infectious destruction.
