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 presence of synthetic dyes such as Methylene Blue (MB) and Methyl Orange (MO) in water sources presents a significant environmental issue, attributed to their stability and toxic properties. This study presents the fabrication and evaluation of a multifunctional ZIF-8/ZnO/Activated Carbon/Nanocellulose composite for its photocatalytic efficiency under optimized conditions. The characterization results confirmed the development of a hierarchical porous structure characterized by an increased surface area, enhanced light absorption, and improved charge separation. Photocatalytic degradation tests demonstrated that the composite attained maximum efficiencies of 91.8% for MB and 87.4% for MO under optimal conditions of pH 7, a catalyst dose of 0.3 g/L, a temperature of 30 °C, and 60 min of UV irradiation. The adsorption behavior conformed to the Langmuir model, exhibiting high monolayer capacities of qmax (53.0 mg/g for MB and 50.1 mg/g for MO), which indicates a strong affinity between the composite and the dye molecules. Kinetic analyses indicated a pseudo-second-order mechanism, and thermodynamic findings validated the spontaneous and exothermic characteristics of the process. The composite exhibited strong stability across five cycles, demonstrating negligible efficiency loss. The interaction between ZIF-8, ZnO, activated carbon, and nanocellulose markedly improved adsorption, charge transfer, and radical generation, rendering this composite an efficient material for sustainable wastewater treatment .
