Impact of bacterial infection on native liver survival in children with cirrhosis due to biliary atresia.
Article in Clinical and experimental pediatrics, 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
Background: Biliary atresia (BA) is a common cause of cirrhosis in children, and serious bacterial infections may worsen clinical outcomes. Purpose: To study the characteristics, associated factors, and outcomes of infections in children with cirrhosis secondary to BA. Methods: A retrospective cohort study was conducted in children aged <18 years with cirrhosis due to BA between 2014 and 2023. Patients were categorized as having proven/suspected bacterial infection, presumed viral infection, or no documented infection. The clinical characteristics, associated risk factors, predictive models, and native liver survival outcomes, including liver transplantation (LT) and death, were analyzed. Results: Among 150 children, 94 (62.7%) had 222 infection episodes and 249 had infection-related diagnosis. Of the 222 episodes, 143 (64.4%) were classified as proven/suspected bacterial infections; cholangitis was the most common bacterial diagnosis (39.7%). Univariate analysis showed that proven/suspected bacterial infection was associated with higher pediatric end-stage liver disease scores at the first visit and during fever episodes and with higher total and direct bilirubin levels during fever episodes. C-reactive protein (CRP) cutoff of 31 mg/L yielded 75.4% sensitivity, 68.2% specificity, and an area under the receiver operating characteristic curve of 0.80 (95% confidence interval [CI], 0.69-0.90) for distinguishing proven/suspected bacterial from presumed viral infections. Overall, 54% of patients underwent LT, 24% survived with their native liver, 8% died, and 14% were lost to follow-up. After adjustment for disease severity and infection history before referral, proven/suspected bacterial infection was associated with lower native liver survival (adjusted hazard ratio, 1.88; 95% CI, 1.51-2.33). Conclusion: Infections are common in children with cirrhosis due to BA. Serum CRP may help distinguish proven/suspected bacterial from other infections. Bacterial infections were associated with lower native liver survival; therefore, appropriate management and prevention may improve native liver survival.
