The qEEG-TIPS score: Development of a predictive model for recurrent overt hepatic encephalopathy after elective TIPS.
Article in JHEP reports : innovation in hepatology, 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 &
aimsOvert hepatic encephalopathy (OHE) continues to be the primary complication following transjugular intrahepatic portosystemic shunt (TIPS) placement. It significantly impairs patients' health-related quality of life, particularly in its recurrent and persistent forms, and may outweigh the benefits of the procedure. This study aimed to develop and internally validate a prognostic score incorporating quantified electroencephalography (qEEG) to predict the risk of post-TIPS recurrent OHE at 3 and 6 months.
methodsWe prospectively enrolled 161 consecutive patients with cirrhosis undergoing elective TIPS for refractory or recurrent ascites or secondary prophylaxis of variceal bleeding. All patients underwent qEEG assessment using validated spectral analysis criteria prior to TIPS placement. A multivariable Cox regression model was constructed to estimate the risk of recurrent OHE. Model performance was evaluated using time-dependent ROC curves, calibration plots, decision curve analysis, and internal validation via bootstrap resampling (B = 1,500).
resultsIndependent predictors of recurrent OHE included age, serum albumin, prior OHE history, and qEEG alterations, which were incorporated into the novel qEEG-TIPS score. The time-dependent AUCs were 0.76 (95% CI 0.70-0.82) and 0.80 (95% CI 0.76-0.85) at 3 and 6 months, respectively. The score identified high-risk patients with a significantly greater incidence of recurrent OHE at 6 months (48% vs. 8% in low-risk patients, p <0.001). Internal validation yielded an optimism-corrected C-index of 0.74 (95% CI 0.69-0.84), indicating mild overfitting but good predictive stability. Decision curve analysis supported the clinical utility of the model.
conclusionsThe qEEG-TIPS score demonstrated good discrimination and calibration in predicting short-term risk of recurrent OHE after TIPS. This tool may assist in risk stratification and guide personalized management both before and after TIPS. IMPACT AND IMPLICATIONS: Recurrent overt hepatic encephalopathy (OHE) is the primary complication of transjugular intrahepatic portosystemic shunt (TIPS) in patients with cirrhosis, markedly reducing quality of life, increasing healthcare burden, and complicating clinical decision-making. This study introduces and internally validates the qEEG-TIPS score, a novel, non-invasive tool integrating quantified electroencephalography with clinical variables to predict the short-term risk of recurrent OHE after elective TIPS. These findings hold particular relevance for patients, hepatologists, and transplant teams as they enable more personalized risk assessment prior to TIPS and may guide decisions on prophylaxis, patient selection, and post-procedural monitoring. If externally validated, the qEEG-TIPS score could enhance clinical pathways by identifying high-risk patients for targeted interventions, supporting more cost-effective and patient-centered TIPS management strategies.
