Development and validation of a minimally invasive diagnostic model for biliary atresia using artificial intelligence.
Article in World journal of pediatrics : WJP, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundUltrasound and serum matrix metalloproteinase-7 (MMP-7) hold great value in distinguishing biliary atresia (BA) from other cholestatic diseases. This study aims to assess the accuracy of an artificial intelligence (AI) based diagnostic model of ultrasound combined with serum MMP-7 in discriminative diagnosis of BA.
methodsThis is a multicenter diagnostic study involving six medical centers in China. Patients with obstructive jaundice were enrolled. A set of morphological operators were employed to extract features of the ultrasound images to construct an AI algorithm. Logistic regression model was established with validation.
resultsTwo cohorts with a total of 348 children with obstructive jaundice were recruited from January 2020 to April 2023. A retrospective cohort of 187 infants served as a training cohort; this included 56 BA and 131 non-BA patients. Serum MMP-7 testing model yielded an area under the receiver-operating characteristic curve (AUROC) of 0.916 [95% confidence interval (CI) = 0.876-0.956], sensitivity of 94.6% (95% CI = 85.1%-98.9%), specificity of 88.6% (95% CI = 81.8%-93.5%), and accuracy of 90.4% (95% CI = 85.2%-94.2%). Values for ultrasound testing model were 0.945 (95% CI = 0.902-0.987), 98.2% (95% CI = 90.5%-99.9%), 91.6% (95% CI = 85.5%-95.7%), and 93.6% (95% CI = 89.1%-96.6%), respectively. The combined AI model obtained an AUROC of 0.985 (95% CI = 0.971-0.999), sensitivity of 98.2% (95% CI = 90.5%-99.9%), specificity of 93.1% (95% CI = 84.4%-96.4%), and accuracy of 94.7% (95% CI = 90.4%-97.4%), respectively. Performance was confirmed using a multicenter prospective validation cohort of 161 patients that included 100 BA cases.
conclusionAn AI model combining ultrasound and serum MMP-7 demonstrated robust high sensitivity and specificity in the differential diagnosis of BA.
