Predictors of Mortality in Patients with Hepatic Encephalopathy: A Retrospective Analysis.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Background Hepatic encephalopathy (HE) is a serious neuropsychiatric complication of liver dysfunction associated with significant morbidity and mortality. Objective The objective of this study was to evaluate the predictors of in-hospital mortality in patients with HE through retrospective analysis. Methods This retrospective observational cohort study was conducted at Punjab Rangers Teaching Hospital, Lahore, Pakistan, from January 2023 to January 2025. A total of 201 adult patients (≥18 years) admitted with a diagnosis of hepatic encephalopathy were included in the study. The diagnosis of HE was made clinically based on the West Haven criteria and supported by biochemical and radiological assessments as needed. Patients with both acute and chronic liver disease were considered, provided they fulfilled the diagnostic criteria for HE. Data were extracted from the hospital's electronic medical record system using a structured questionnaire. Clinical and laboratory parameters were analyzed to identify predictors of in-hospital mortality using multivariate logistic regression. Results The in-hospital mortality rate was 57 (28.4%). Non-survivors had significantly higher Model for End-Stage Liver Disease (MELD) scores (mean 29.3 vs. 24.9, p < 0.001), elevated serum ammonia levels (mean 136.2 µmol/L vs. 103.1 µmol/L, p < 0.001), more frequent renal dysfunction (37 (64.9%) vs. 41 (28.9%), p < 0.001), and hyponatremia (33 (57.9%) vs. 43 (29.6%), p = 0.002). High-grade HE (Grade III/IV) was more prevalent among non-survivors (42 (73.7%) vs. 52 (36.2%), p < 0.001). Independent predictors of mortality included MELD score ≥28, serum ammonia ≥120 µmol/L, renal dysfunction, serum sodium <130 mEq/L, and high-grade HE. The MELD score demonstrated the highest discriminatory ability (area under the curve (AUC) = 0.78). Conclusion In patients with HE, higher MELD scores, elevated serum ammonia, renal impairment, hyponatremia, and advanced HE grades are significant predictors of mortality. These findings highlight the importance of early risk assessment and may guide decisions regarding intensive management and liver transplant referral.
