Delayed Intrathoracic Textile Foreign Body Following Penetrating Shrapnel Injury Presenting with Expectoration of Fabric-Like Material and Chronic Middle-Lobe Destruction: A Case Report.
Article in International medical case reports journal, 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
Background: Retained intrathoracic and tracheobronchial foreign bodies are uncommon but important causes of chronic respiratory symptoms. Diagnosis may be delayed because presentations are nonspecific and retained textile material is often radiolucent. Such material can lead to chronic infection, pleural adhesions, and progressive lung destruction. Case Presentation: A 31-year-old Syrian male military serviceman and active smoker (20 pack-years) presented with a long-standing intermittent cough that had worsened over one week and become productive of white sputum. He also reported a single episode of expectorating suspected textile material, along with fatigue, weakness, and night sweats, but no fever, dyspnea, hemoptysis, or chest pain. Years earlier, he had sustained a penetrating shrapnel injury complicated by pneumothorax and later purulent pleural effusion requiring tube thoracostomy. On admission, examination suggested right basal involvement; laboratory studies were unremarkable, and tuberculosis testing was negative. Chest CT showed a heterogeneous right-sided lesion with right middle-lobe atelectatic change and tree-in-bud opacities, suggesting chronic inflammatory or infectious disease. Bronchoscopy revealed friable, bleeding mucosa and distortion at the right middle-lobe bronchial orifice. Case discussion: Due to persistent symptoms and chronic localized abnormalities, right thoracotomy was performed. Dense pleural adhesions were found, and an intrathoracic textile foreign body was removed, most likely implanted during the prior traumatic injury. The right middle lobe was extensively destroyed with purulent change, requiring right middle lobectomy. Histopathology showed fibrosis, architectural destruction, fibroblastic foci, honeycomb change, and chronic inflammation consistent with a UIP pattern; adhesion fragments showed acute-on-chronic foreign body-associated inflammation. Conclusion: Radiolucent textile foreign bodies may remain undetected for years after penetrating thoracic trauma and later present with chronic respiratory symptoms and localized destructive infection. Once irreversible damage is established, thoracotomy with foreign body removal and lobectomy may be necessary.
