Bacterial versus parasitic liver abscesses in children: a retrospective cohort study of clinical and laboratory differences.
Article in BMC 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
backgroundThis study aimed to describe the clinical and laboratory differences between bacterial and parasitic liver abscesses in pediatric patients.
methodsWe retrospectively reviewed all pediatric cases of liver abscess diagnosed and treated at the National Children's Hospital (NCH), Hanoi, between January 2018 and July 2024. Clinical characteristics, laboratory parameters, and imaging findings were compared between bacterial and parasitic etiologies.
resultsThis retrospective study included 80 children aged 1 month to 15 years diagnosed with liver abscess between 2018 and 2024. Overall, 85% of the patients resided in rural or mountainous areas, 60% were male, and nearly all (95%) were older than 6 months. Bacterial abscesses were significantly associated with high-grade fever (90.3% vs. 36.7%; p < 0.005), hepatomegaly (87.1% vs. 63.3%; p < 0.05), and splenomegaly (22.6% vs. 4.1%; p < 0.05). Patients with bacterial abscesses presented increased neutrophil percentages (61.5%), whereas those with parasitic abscesses presented a markedly increased incidence of eosinophilia > 10% (81.6% vs. 9.7%). Elevated CRP levels (> 100 mg/L) were more common in bacterial cases than in parasitic cases (54.8% vs. 24.5%). On imaging, solitary lesions were more common in bacterial abscesses (58.1%), whereas multiple cavities predominated in parasitic infections (73.5%).
conclusionLiver abscesses affected children most significantly in the over 6-month old and were more common in males, particularly those from rural or mountainous areas. Nonspecific presentations hinder early diagnosis; however, clinical features including high fever and hepatosplenomegaly, CRP levels, eosinophil counts, and characteristic imaging findings may assist in distinguishing bacterial from parasitic etiologies and support earlier targeted management.
