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

This research presents the development of a novel electrospun nanofibrous membrane that combines chitosan (CS), polycaprolactone (PCL), and a bimetallic lanthanum-rubidium metal-organic framework (La/Rb-MOF) for the effective extraction of hexavalent chromium [Cr(vi)] from water. The La/Rb-MOF/CS-PCL membrane was created under optimized electrospinning parameters to improve both mechanical durability and adsorption capabilities. Detailed structural and surface analyses conducted through methods such as XRD, FTIR, XPS, SEM, and EDX confirmed the successful integration of La-Rb-MOF into the nanofibrous network, resulting in a porous and chemically reactive structure. Batch adsorption tests indicated that factors such as pH, adsorbent dosage, temperature, and initial Cr(vi) concentration significantly affected the removal efficiency. The adsorption kinetics were best modeled by the pseudo-second-order model, while the equilibrium data adhered to the Langmuir isotherm, achieving a maximum adsorption capacity of 449.2 mg g
