Analysis of Risk Factors and Development of a Predictive Nomogram for Bronchiolitis Obliterans in Children With Severe Adenovirus Pneumonia: A Retrospective Study.
Article in Canadian respiratory journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundBronchiolitis obliterans (BO) is a rare chronic pulmonary condition in pediatric patients, characterized by irreversible fibrotic constriction of the small airways. This study aims to analyze the risk factors for BO caused by severe adenovirus pneumonia (SAP) and to develop a nomogram model for personalized prediction.
methodsWe retrospectively analyzed 251 children with SAP admitted to the Children's Hospital of Nanjing Medical University between January 2017 and March 2024. Among them, 77 were classified into the BO group and 174 into the non-BO group. A predictive nomogram was developed based on independent risk factors identified through univariate analysis, least absolute shrinkage and selection operator (LASSO) regression, and multivariate logistic regression.
resultsMultivariable analysis identified the following independent risk factors for BO: wheezing (odds ratio [OR] = 4.78; 95% confidence interval [CI], (2.00∼11.40); p < 0.001), large lobar consolidation (OR = 8.53; 95% CI, 3.63∼20.02; p < 0.001), length of hospital stay (OR = 1.20; 95% CI, 1.08-1.33; p < 0.001), and duration of fever (OR = 1.20; 95% CI, 1.09-1.32; p < 0.001). Mechanical ventilation showed a trend toward increased risk but did not reach statistical significance (OR = 5.35; 95% CI, 0.74-38.56; p = 0.096). The nomogram demonstrated excellent discriminative ability, with an area under the curve of 0.90 (95% CI: 0.85-0.94). Calibration curves indicated good agreement between predicted and observed outcomes. Decision curve analysis showed a net clinical benefit within a clinically relevant threshold probability range of 0.10-0.70.
conclusionsA nomogram incorporating five independent risk factors-wheezing, duration of fever, length of hospital stay, mechanical ventilation, and large lobar consolidation-was developed to predict BO risk in children with SAP.
