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 conventional chemical bleaching of pulp generates substantial environmental burdens due to toxic effluents and high chemical consumption. This study explores a sustainable alternative through the enzymatic biobleaching of pineapple leaf fiber (PALF) pulp using crude laccase extracted from Paramarasmius palmivorus, a white-rot fungus. The effects of enzyme dosage (1-10 U/g pulp) and reaction time (2-10 h) on pulp quality were systematically optimized using Response Surface Methodology (RSM). Key pulp properties, including Kappa number, brightness, and intrinsic viscosity, were evaluated and compared to chemical bleaching using hydrogen peroxide (H
