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

Toxic metals and metalloids (TMMs) in soil can be accumulated in crops, which poses potential risks to human health. In this paper, 55 topsoil and 23 crop samples, collected in Qilihe, China, were selected to study the contamination, risk, and plant accumulation of TMMs in soil-crop system. TMM concentrations in soil samples were all below the permissible limits, but Hg and Cd exhibited the potential ecological risk due to their slight accumulation in soil. There was slight Hg pollution in 2 samples of Lanzhou lily (Lilium davidii), and 1 sample of radish (Raphanus sativus), Chinese cabbage (Brassica pekinensis), and welsh onions (Allium fistulosum) due to Hg's strong bio-accumulation, but there was no risk to human health. The TMM accumulation in leaf crops was large, followed in tuber and seed crops. Available potassium, cation exchange capacity, soil organic matter, and available phosphate were the main factors associated with TMM accumulation in crops among the selected soil properties. This study shows the current contamination situation and the predominant influencing factors associated with the accumulation of TMMs in 24 crops, which provides the emphasis and direction of relative policies in land use and crop plantation.
