1 · What the graph read from it

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.

2 · The registry

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

In this work, a novel, eco-friendly composite material composed of MgAl-layered double hydroxide and cuttlebone (LDH/CB) was synthesized for the efficient adsorption of Congo Red dye from aqueous solutions. The LDH/CB composite was synthesized via a one-step co-precipitation method, and its crystallinity was confirmed by X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR). The effects of key experimental parameters—including pH, contact time, and initial dye concentration—on the adsorption efficiency were systematically investigated. The adsorption kinetics followed the pseudo-first-order model, while the equilibrium data were well described by the Langmuir and D–R isotherm, with a maximum adsorption capacity of 380 mg/g. Thermodynamic analysis revealed that the adsorption process was spontaneous, exothermic, and primarily driven by electrostatic interactions. Moreover, the composite exhibited excellent reusability over five adsorption–desorption cycles, maintaining high stability in performance. These findings highlight the potential of the LDH/CB composite as an efficient and sustainable adsorbent for the treatment of dye-contaminated wastewater.
