Pediatric Congenital Tracheobronchial Variants and Their Clinical Significance for Endotracheal Intubation and Airway Management: A Scoping Review of Fetal, Neonatal, and Pediatric Cases.
Review in Cureus, 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
Congenital tracheobronchial variants (CTBVs) may distort airway landmarks, alter carinal recognition, and complicate ventilation during pediatric endotracheal intubation. Although uncommon, these anomalies can create important peri-intubation risks that are often underrecognized. This scoping review was conducted in accordance with the Joanna Briggs Institute methodology and Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidance. Using a Population-Concept-Context framework, we identified human case reports and small case series describing congenital tracheal or bronchial anomalies relevant to intubation, bronchoscopy, ventilation, or airway planning. Searches were performed in PubMed, Scopus, and Web of Science, with additional studies identified through manual searching. Sixty-six records were identified. After removal of one duplicate, 61 records from the database search were screened, 42 were excluded, and 23 full-text reports were assessed. Twenty studies were included, comprising 18 case reports and two small case series. Six studies described tracheal agenesis or atresia, four bronchial atresia, three tracheal bronchi, three bridge bronchi with or without pulmonary artery sling, and four bronchial isomerism or laterality defects. Cases ranged from 21 weeks of gestation to 15 years of age. Tracheal agenesis or atresia produced the most severe cannot-intubate presentations. Fixed stenotic lesions increased risks during tube passage and sizing, whereas distal anomalies more commonly mimicked selective intubation, mucus plugging, or refractory wheeze. CTBVs have important implications for pediatric airway management. Pre-intubation anatomical assessment and early bronchoscopic confirmation may reduce avoidable complications and support safer individualized airway planning.
