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

The adsorption and oxidation of arsenite [As(III)] by soil components are critical processes that influence its toxicity and mobility. However, the specific mechanisms driving the synergistic interactions among bacteria, soil minerals, and humic acid (HA) in these processes remain insufficiently understood. This study investigated the effects of goethite and HA association on As(III) adsorption-oxidation by the As(III)-oxidizing bacterium SY8 using batch incubation experiments and spectroscopic analyses. The results indicated that goethite inhibited the growth of SY8, but its binary and ternary composites with HA and SY8 substantially enhanced the adsorption and oxidation of As(III) compared to SY8 alone. This enhancement could be attributed to the generation of hydroxyl radicals (·OH) through Fenton-like reactions that contribute to the enhanced oxidation of As(III). The Fenton-like reactions involved interactions between H
