The role of multifocal visual evoked potential in detection of minimal hepatic encephalopathy in patients with compensated liver cirrhosis.
Article in BMC neurology, 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
backgroundMinimal hepatic encephalopathy (MHE) is one of the most debilitating complications of hepatic cirrhosis, and visual electrophysiology, visual evoked potential (VEP) has long been used for MHE diagnosis. This technique only produces a summed response that is greatly dominated by the macular region. Multifocal visual evoked potential (mfVEP) imaging minimizes these limitations because it allows topographic recording of the optic nerve and visual cortex. The aim of this study was to detect minimal hepatic encephalopathy among cirrhotic patients using the mfVEP in comparison to the validated psychometric hepatic encephalopathy score (PHES), paired associative learning (PAL) and the Benton visual retention test (BVRT).
methodsForty-five patients with compensated hepatic cirrhosis were enrolled in our study and compared to 45 normal controls who were matched for age, sex and educational level. Both groups underwent psychological tests (PHES, PAL, BVRT) and neurophysiological tests (mfVEP).
results1According to the validated PHES, 14 patients were found to have MHE, 15 patients were found to have abnormal mfVEP, and abnormalities in the BVRT and PAL were found in 11 and 10 patients, respectively. 2-mfVEP showed the highest sensitivity in the detection of MHE in reference to the PHES. 3- The mfVEP test and potentially the BVRT have the advantage of detecting subtle abnormalities in non-MHE cirrhotic patients, for further research and follow-up are needed.
conclusionmfVEP demonstates promising results for objective early detection of MHE, with a sensitivity of approximately 92.9%.
