Pulmonary Langerhans cell histiocytosis: A case series and literature review.
Article in Journal of clinical imaging science, 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
Pulmonary Langerhans cell histiocytosis (PLCH) is a rare diffuse parenchymal lung disease representing 3% of all interstitial lung diseases. PLCH occurs either as part of multi-system Langerhans cell histiocytosis (LCH) or an isolated disease of the lung. Isolated involvement of lungs is observed in approximately 50-70% of LCH cases and the age of onset peaks between 20 and 40 years without gender difference. Cigarette smoking is the only identified environmental risk factor. PLCH is characterized by Langerhans cell infiltrates that in general are in a bronchiolocentric distribution. Pulmonary lesions can occur after chronic systemic disease or are an initial sign of disease. The aims of this study are to (1) report five rare cases of PLCH in adults; (2) discuss the relationship of PLCH with interstitial lung fibrosis; (3) provide a concise review of PLCH epidemiology, pathophysiology, diagnosis, treatment, and prognosis to improve the knowledge of PLCH by pneumologists and internal medicine physicians.
