Prediction of pulmonary artery sling in children using echocardiography: scoring based on pulmonary artery bifurcation and pulmonary valve ring distance.
Article in Cardiovascular ultrasound, 2025. 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
objectiveTo analyze the echocardiography characteristics of pulmonary artery sling (PAS) and explore the diagnostic value of the distance between the bifurcation of the left and right pulmonary arteries and the pulmonary artery valve annulus (DBP) in diagnosing PAS in children.
methodsThis retrospective study analyzed echocardiographic data from 27 children diagnosed with PAS at our hospital from March 2014 to December 2022. The data were compared with those from 77 normal children. The study examined statistical differences between the two groups in the diameters of the left and right pulmonary arteries, the main pulmonary artery valve annulus diameter, and the DBP, both uncorrected and corrected for body surface area (BSA). The diagnostic utility of these measurements for distinguishing children with PAS from those without was assessed using receiver operating characteristic (ROC) curves.
resultsThe DBP and the corrected DBP values were significantly higher in the PAS group than in the normal group, with areas under the ROC curve of 0.909 for DBP and 0.951 for DBP/BSA (P < 0.05). A DBP of 1.87 cm as the diagnostic threshold yielded a sensitivity of 98.9% and specificity of 84.4%. A DBP/BSA of 7.68 cm/m
conclusionThe pivotal element in echocardiography diagnosis of PAS is the identification of the spatial relationship between the left pulmonary artery (LPA) and the trachea. The use of quantitative indices such as DBP and DBP/BSA for adjunctive diagnosis can positively impact the early detection of PAS.
