Telomere biology disorders associated with childhood interstitial lung disease.
Article in Clinical and experimental pediatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: Telomere biology disorders (TBDs) are rare inherited defects in telomere maintenance associated with multisystem diseases. Although pulmonary fibrosis has been well described in adults, data remain limited on childhood interstitial lung disease (chILD) related to TBDs. Purpose: This study aimed to characterize the pulmonary phenotype, genetic spectrum, and clinical course of pediatric TBD-associated chILD. Methods: We performed this registry-based cohort study using the European chILD-EU database to identify children with telomere maintenance gene variants. Their clinical data, longitudinal outcomes, telomere length (quantitative polymerase chain reaction), high-resolution computed tomography (HRCT), and histopathology findings were systematically analyzed. Results: Ten children were identified with genetically confirmed or suspected TBDs harboring variants in TERT, TERC, WRAP53, DKC1, PARN, and RTEL1. Telomere length was below the 1st age-adjusted percentile in 6 of the 8 tested patients. The HRCT findings were heterogeneous and included ground-glass opacities, reticular changes, cystic lesions, and emphysema. The histopathological patterns included cellular nonspecific interstitial pneumonia, usual interstitial pneumonia, follicular bronchiolitis, and pleuroparenchymal fibrosis. The disease course was frequently severe: 7 of the 10 patients required long-term oxygen therapy, 3 underwent hematopoietic stem cell transplantation, and 4 died during follow-up. Conclusion: TBD-associated chILD is a rare but clinically aggressive multisystem disorder with a broad radiological and histopathological spectrum. Early genetic testing and multidisciplinary management are essential since affected children may experience rapid disease progression and substantial mortality.
