Nutritional Characterization of Brewer's Spent Grains Depending on Brewery Scale and Beer Production Technology.
Article in Foods (Basel, Switzerland), 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
Brewers' spent grains (BSGs) represent a significant by-product of beer production, yet their detailed compositional variation across brewery scales and beer technologies remains insufficiently explored. This study systematically characterized eleven BSG samples from Latvian breweries of diverse capacities and beer styles, assessing macronutrient profiles, amino acid content, phenolic compounds, and antioxidant activity. The results revealed considerable compositional heterogeneity: the moisture content ranged 71.9-83.9%, crude protein 17.8-30.83%, lipids 0.68-5.44%, and dietary fiber 59.61-71.64% of dry weight. All samples contained a complete set of essential amino acids, and the highest total phenolic content was observed in dark beer BSGs, which was up to 1.6 times higher than in light beer. Notably, a significant negative correlation was found between ABTS antioxidant activity and total phenolic content, indicating complex matrix interactions. These findings demonstrate a marked variation in BSG composition and underscore the impact of brewery parameters on nutritional and functional values, supporting efficient, tailored valorization strategies for functional food production.
