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

Mn oxide minerals have a large specific surface area and structural vacancies, which have attracted increasing attention in the remediation of Cd-contaminated soil. Vernadite, as a kind of common Mn oxide mineral, was applied to Cd-contaminated red soil to carry out a passivation experiment, to evaluate the remediation effect on Cd. After applying 0.2-4% vernadite to Cd-contaminated red soil and passivating it for 90 d, the soil pH value increased by 0.17-1.29 units, the soil cation exchange capacity (CEC) increased by 11.86-62.25%, and the soil organic matter decreased by 3.42-31.09%. The Cd-contaminated soil with 4% vernadite had the best passivation effect on Cd, which significantly reduced the activity of Cd in the soil. The available Cd content in the soil decreased from 3.22 mg kg
