Activated carbons from brewers spent grain improve Orange II removal through combined adsorption and enzymatic oxidation.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The brewing industry generates large amounts of brewer's spent grain (BSG), which poses environmental challenges due to improper disposal. While BSG has been studied as a dye adsorbent, its conversion into activated carbons (ACs) for dye removal via both adsorption and enzymatic oxidation remains underexplored. Moreover, prior studies rarely distinguish the individual roles of adsorption and enzymatic catalysis in dye removal. This study addresses these gaps by producing eco-friendly ACs from BSG through non-conventional chemical activation and evaluating their dual functionality in Orange II removal using immobilized horseradish peroxidase. Activation at 400-600 °C and NaOH/BSG mass ratios of 1:1 to 3:1 increased surface area (3.46-466 m
