Consolidation in the right middle lobe in pediatric bronchial-pulmonary artery shunt: radiology's Aunt Minnie?
Article in Diagnostic and interventional radiology (Ankara, Turkey), 2025. 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
purposeBy retrospectively studying the chest computed tomography (CT) data of children with bronchial artery (BA)-pulmonary artery fistula, this study summarizes the characteristic imaging features of the disease and provides imaging support for the diagnosis and clinical treatment of these children.
methodsDigital subtraction angiography and CT angiography data were collected from 74 children with pulmonary hemorrhage following BA embolization. Bronchial-pulmonary shunt was present in 30 cases.
resultsOf the 74 children with pulmonary hemorrhage in this study, seven exhibited signs of consolidation in the middle lobe of the right lung, and bronchial-pulmonary shunt existed in all of them. A total of 30 children with BA-pulmonary artery shunt (PAS) had BA tortuosity and thickening. Regarding primary BA-PAS, the middle lobe and lower lobe of the right lung were involved in 94.1% (16) of the children. Those with a fistula located in the middle lobe of the right lung accounted for 58.8% (10 cases), of which 40.0% (four cases) presented consolidation. In this study, 41.2% (seven) of the children with primary BA-PAS exhibited no abnormal changes on chest CT, and 58.8% (10 cases) exhibited abnormal changes in the unilateral lung.
conclusionFor children with pulmonary hemorrhage who have consolidation in the right middle lobe, the formation of BA-PAS should be anticipated. The possibility of primary BA-PAS should not be disregarded in children with pulmonary hemorrhage with tortuosity and dilation of BAs, despite no apparent abnormalities on lung CT, or ground-glass density or consolidation on only one side. CLINICAL SIGNIFICANCE: The chest CT of patients with pulmonary hemorrhage showed consolidation of the right middle lobe of the lung, which was highly likely to indicate BA-PAS.
