Congenital bronchobiliary fistula in a newborn: a case report.
Article in Journal of medical case reports, 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
backgroundCongenital bronchobiliary fistula (CBBF) is a developmental structural abnormality between the trachea or bronchus and the biliary tree, with non-specific clinical manifestations that mainly present as repeated cough and dyspnea, but it is often misdiagnosed as pneumonia. If not promptly diagnosed and effectively treated, CBBF can be fatal. Currently, radical surgery is the only treatment option for CBBF. CASE PRESENTATION: An 8-day-old full-term Han Chinese female infant presented with coughing accompanied by sputum and shortness of breath with worsening dyspnea for 4 days. Yellowish green sputum was seen during invasive ventilation. A follow-up chest radiograph suggested a solid lesion in the right upper lung. Airway malformations and an abnormal opening in the middle of the tracheal eminence were observed by fiberoptic bronchoscopy. Chest computed tomography (CT) and tracheal imaging showed a fistula below the tracheal bulla traveling towards the liver and communicating with Glisson's capsule at the hepatic hilum, suggesting the presence of a tracheobiliary fistula. Intraoperatively, a fistula was seen extending from the tracheal eminence to the esophageal hiatus, and trans-fistula imaging showed that the contrast agent entered the intestines through the biliary tree, confirming the diagnosis of a CBBF, which was removed. The pathology was consistent with a bronchial fistula. The ventilator was withdrawn on postoperative day 10. Following discharge, the patient recovered well with good growth and development, and no symptoms of lung or digestive tract discomfort.
conclusionCBBF is frequently misdiagnosed. Bronchoscopy remains the preferred diagnostic modality for definitive confirmation.
