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

Long-root Eichhornia crassipes, an aquatic plant with extensive root systems, has demonstrated potential in remediating eutrophicated water bodies. However, improper disposal of large quantities of discarded plants post-remediation can easily cause secondary pollution. In this study, rapidly recoverable magnetic carbon quantum dots (MCQDs) were greenly synthesized via hydrothermal treatment of long-root Eichhornia crassipes and subsequent coupling with Fe3O4 nanoparticles. Adsorption experiments demonstrated that MCQDs displayed a commendable adsorption capacity for various heavy metals in municipal wastewater under the synergistic effect of CODs and Fe3O4. Mechanistic analyses revealed that the adsorption involved chemical binding with oxygen-containing functional groups and amino groups on the surface of MCOQs. The saturated MCQDs were efficiently recovered within 5 min using an applied magnetic field, offering a practical solution for nanoparticle recovery. This study provides valuable insights into the green resource utilization of Long-root Eichhornia crassipes based on CQD technology.
