Article in Chemistry, an Asian journal, 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
Volatile aldehydes, especially from cigarette, pose potential threats to human health. However, the current strategies failed to selectively adsorb aldehyde hazards, indiscriminately removing all the substances to reduce smoking satisfaction. In this work, we have uniformly localized layered double hydroxides (LDH) onto the cellulose acetate (CA) fiber to prepare LDH@CA composites based on the hydrogen bonds between the ester carbonyl groups of CA and the hydroxyl groups of LDH. The acquired hierarchical structure exhibited abundant hydroxyl groups, forming hydrogen bonds with aldehydes for a specific adsorption. Note that 73.03% of formaldehyde and 86.23% of acetaldehyde could be effectively removed by the composite. More importantly, the composites could selectively remove the aldehydes without reducing nicotine in the cigarette. Accordingly, we could use the composite to maintain the smoking satisfactory while removing hazardous aldehydes. Therefore, we have realized the selective and specific adsorption of aldehydes by LDH-modified CA based on the hydrogen bonds. It is expected that the as-prepared low-cost, and environmentally friendly composite could find more applications for air purification.
