Heavy metal adsorption by graphene oxide modified with 5-amino-3(2-thienyl)pyrazole using central composite design/response surface methodology (CCD/RSM).

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
In this study, graphene oxide (GO) was chemically functionalized with 5-amino-3(2-thienyl)pyrazole (5-ATP), introducing oxygen-, nitrogen-, and sulfur-containing groups, to enhance adsorption performance and develop a multifunctional adsorbent (5-ATP-GO) for efficient removal of Cd(ii), Hg(ii), and As(iii) from aqueous solutions. The GO and 5-ATP-GO composites were characterized by Fourier transform infrared spectroscopy, field-emission scanning electron microscopy, thermogravimetric analysis, X-ray diffraction, energy-dispersive X-ray spectroscopy, Brunauer-Emmett-Teller analysis, Raman spectroscopy, and zeta potential analysis. The performance of 5-ATP-GO for heavy metal removal was evaluated by design of experiment to optimize operational parameters and assess adsorption capacity. Central composite design/response surface methodology analysis was applied for the optimization of adsorbing conditions, (
