The predictive value of fibrosis profiles for hepatitis E virus-related liver failure among hospitalized patients with acute hepatitis E: a retrospective cohort study.
Article in BMC infectious diseases, 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
backgroundHepatitis E virus (HEV) infection is an important etiology of liver failure. This study aimed to explore the associations of blood fibrosis profiles with HEV-related liver failure (HEV-LF) onset and evaluate their prediction performance in hospitalized patients with acute hepatitis E.
methodsParticipants were obtained from two tertiary medical centers in Jiangsu, China, between January 2018 and November 2024. Cox proportional hazards regression, restricted cubic splines, and threshold effect analysis were used to examine associations between fibrosis markers and HEV-LF risk. The predictive value of these markers was evaluated for importance ranking, discrimination, calibration, and net benefit.
resultsAmong 504 included participants, 59 developed HEV-LF during hospitalization. After adjusting for covariates, elevated baseline laminin (HR = 1.432, 95% CI: 1.080-1.900), fibrosis-4 score (HR = 1.865, 95% CI: 1.375-2.530), and aspartate aminotransferase to platelet ratio index (APRI) (HR = 1.603, 95% CI: 1.315-1.954) were associated with a higher HEV-LF risk in a dose-dependent manner. Hyaluronic acid (≤ 740 ng/mL: HR = 1.797, 95% CI: 1.177-2.744) and type IV collagen (≤ 137 ng/mL: HR = 3.075, 95% CI: 1.709-5.533) showed nonlinear associations. APRI was ranked the highest in importance, and its combination with the other two top important markers provided good discrimination (7-day HEV-LF: AUROC = 84.98%, 95% CI: 78.55-91.41; 14-day HEV-LF: AUROC = 80.11%, 95% CI: 73.49-86.73), calibration, and clinical utility for predicting HEV-LF onset.
conclusionsSeveral blood fibrosis markers are closely associated with HEV-LF risk and have promising predictive value. These findings may inform clinical risk stratification in patients with AHE.
