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
Backgrounds & Aims: Overt hepatic encephalopathy (OHE) is the most feared complication after transjugular intrahepatic portosystemic shunt (TIPS) placement. We aimed to evaluate the usefulness of the animal naming test (ANT) in predicting the occurrence of OHE after elective TIPS placement. Methods: The ANT (1 min) was evaluated before TIPS, at discharge, and at 1, 3, and 6 months in all patients treated with elective TIPS between September 2019 and November 2024. Results: We included 100 consecutive patients (80% men; median age 59 years; median MELD score 11). Indications for TIPS were ascites, secondary prophylaxis, hydrothorax, and pre-surgery in 63%, 19%, 5%, 13%, respectively; 24% had a history of OHE. The median ANT before TIPS was 21 (IQR 17-27). The cumulative incidence of OHE was 30%, considering death and liver transplantation as competing events. In multivariate analysis, independent predictors of OHE development were age (hazard ratio [HR] 1.04; 95% CI 1.00-1.09; Conclusion: ANT at discharge may be useful in identifying patients at higher risk of OHE after TIPS. Impact and implications: Overt hepatic encephalopathy (OHE) remains a major limitation of transjugular intrahepatic portosystemic shunt (TIPS) placement. While the animal naming test (ANT) before TIPS could not accurately predict the development of OHE, both ANT and ammonia after TIPS were predictive of OHE. Each decrease of ANT of 1 point was associated with an increased risk of OHE of 8%. Incorporating this test into routine post-procedural assessment could improve early identification of high-risk patients, guide preventive strategies, and optimize follow-up.
