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

Waters contaminated with toxic hexavalent chromium [Cr(VI)] can contain co-occurring metals and organic compounds, promoting simultaneous redox, complexation, and precipitation reactions. This study systematically investigates how Fe minerals, aqueous Fe(II) and Cu(II), and various low molecular weight organic compounds induce Cr(VI) adsorption, reduction, and precipitation reactions. Through batch and column experiments and microscopic and spectroscopic analyses, we determine how aqueous metals and organic compounds interact with Cr(VI) to promote sequestration or release of Cr adsorbed to iron (oxyhydr)oxides. Aqueous Cu precipitates from solution, which removes Cr(VI) from the water column, but may prevent some Cr(VI) from being reduced. With the addition of ascorbic acid, Cu can be mobilized as Cu(0) colloids with Cr also being released. Aqueous Fe(II) promotes Cr(VI) reduction, but also may mobilize Cr associated with reacted Fe (oxyhydr)oxides. The results identified in our study provide insights about overlooked reactions that can control the sequestration and release of Cr in contaminated waters containing complex mixtures of inorganic and organic chemicals which have relevant implications for remediation strategies and recovery of critical minerals.
