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
Lignin-based materials are attracting increasing attention for their effectiveness in treating polluted water. In this study, special emphasis is placed on hydrogels modified with lignin extracted from Poplar and Ayous (Alpi Spa wood waste) which were developed for the removal of organic dyes, using methylene blue as a model pollutant. The two types of wood differ notably in their characteristics. Poplar is a medium-density hardwood with a relatively low lignin content, higher water repellence, and good ability to be shaped and glued. Ayous is a tropical wood; its lignin has a different chemical makeup, offering greater resistance to microbial degradation. However, Ayous is more prone to moisture absorption and less durable outdoors if untreated. The lignins covalently incorporated into polyvinyl alcohol (PVA)-based hydrogel via direct esterification with polyamide epichlorohydrin (PAE) were investigated. This chemical crosslinking strategy significantly reduced lignin leaching. The resulting hydrogels were thoroughly characterized by ATR-FTIR spectroscopy, thermogravimetric analysis, and scanning electron microscopy to elucidate their structure and morphology. Batch adsorption experiments revealed that hydrogels incorporating lignin from Ayous hardwood waste achieved remarkable methylene blue removal efficiency (up to 88%), a substantial improvement over both hydrogels incorporating commercial lignin (64%) and unmodified hydrogel (9%). By integrating lignin's adsorption capabilities with the porosity and recoverability of the hydrogel matrix, the Ayous lignin-modified hydrogels present a highly promising and sustainable solution for eliminating organic pollutants from wastewater. This innovative approach not only enhances pollutant removal but also promotes environmental sustainability and aligns with circular economy principles.
