Study on the gasification characteristics of wool in supercritical water for hydrogen production.
Article in RSC advances, 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
Waste wool, a protein-based waste from textile and livestock industries, represents a promising yet underexplored feedstock for clean hydrogen production. In supercritical water, its keratin structure undergoes rapid hydrolysis and depolymerization, enabling efficient conversion into hydrogen-rich gas with minimal char formation. In this study, a systematic investigation of wool SCWG was conducted by evaluating the effects of temperature, feedstock concentration, residence time, and catalyst addition. Compared with conventional biomass feedstocks, the unique protein structure of wool leads to distinct gasification behavior and high hydrogen production potential. Higher temperature, lower feedstock concentration, and moderately long residence time significantly enhance carbon conversion and gas yield. Under optimal conditions (600 °C, 2 wt% feedstock concentration, and 5 min residence time), carbon conversion efficiency reached 95.71%, hydrogen efficiency reached 119.26%, and gas yield reached 42.72 mol kg
