Nitrogen Oxide Inhalation Lung Injury From an Industrial Explosion: A Case Report and Review of the Literature.
Article in Cureus, 2025. 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
An industrial explosion released nitrogen oxide, which a 43-year-old man inhaled at work. He developed cough and exertional dyspnea without hypoxemia, and chest computed tomography obtained two days after exposure showed poorly defined centrilobular ground-glass nodules predominantly in the lingular and lower lobes. Bronchoalveolar lavage revealed an increased total cell count with mild lymphocytosis. Transbronchial lung biopsy demonstrated type II pneumocyte hyperplasia, mural thickening with focal fibrosis, and fibrin deposition consistent with centri-acinar dominant alveolitis. Supportive care without corticosteroids led to clinical and radiologic resolution. This case highlights the latent onset pattern after nitrogen oxide inhalation and provides clinicoradiologic-pathologic correlation for a mild presentation, suggesting that careful observation may be reasonable when oxygenation is preserved and no progression is observed.
