The effect of a plant- and dairy-based protein diet on serum levels of inflammatory and oxidative stress biomarkers in patients with liver cirrhosis: a randomized controlled trial.
Trial report in BMC gastroenterology, 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
backgroundPrevious studies have confirmed that plant and dairy proteins help with hepatic encephalopathy; yet, the impact on oxidative stress and inflammation in liver cirrhosis remains unexplored. This is the first interventional clinical trial investigating the impact of a plant and dairy protein diet on oxidative stress and inflammatory biomarkers in cirrhotic patients.
methodsIn this controlled randomized clinical trial, 46 patients with cirrhosis were divided into two groups to receive a prescribed diet based on vegetable and dairy proteins (intervention group, n = 23) or a standard isocaloric diet (control group, n = 23) for 12 weeks. Anthropometric indicators, physical activity level, inflammatory biomarkers including serum levels of high sensitive C-reactive protein (hs-CRP), tumor necrosis factor-alpha (TNF-α), and interleukin 6 (IL-6), as well as oxidative stress status including serum malondialdehyde (MDA), total antioxidant capacity (TAC), and total oxidant status (TOS) were evaluated before and after the intervention. Dietary intake was also assessed before, during, and after the intervention.
resultsBased on the findings of this study, consuming a diet based on plant and dairy protein significantly reduced the Model for End-Stage Liver Disease (MELD) score (P < 0.05). No significant changes were observed in anthropometric parameters, including body mass index, mid-arm muscle circumference, and triceps skinfold thickness, as well as serum levels of inflammatory biomarkers (hs-CRP, TNF-α, and IL-6) and oxidative stress biomarkers (MDA, TOS, and TAC).
conclusionFollowing a diet based on plant and dairy proteins for 12 weeks in patients with cirrhosis caused a reduction in MELD score, which may indicate meaningful clinical improvement in disease severity even without significant changes in inflammatory and oxidative stress biomarkers.
