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

Mining activities often bring great pressure to the surrounding ecological environment, so it is necessary to carry out ecological restoration in mining areas. In this study, a constructed technosol (denoted SAS) for ecological restoration was prepared with municipal sludge as main materials, and its properties and ecological risk was assessed. The results showed that the optimal conditions for preparation were as follows: raw material ratio of 0.04, water-cement ratio of 0.01, aluminum powder dosage of 0.03%, curing temperature of 40 ℃, curing time of 24 h. The solidification of cement contributed to the connection path between the sludge particles, and the bubbles generated by aluminum powder further formed the microscopic pore structure. Heavy metals chemical species analysis concluded that As, Cd and Pb were immobilized, while Cu and Ni were tended to be activated, assessment result indicated low risk level. The transformation of macromolecular organic matter into humus was beneficial to improve the structure and biological activity, and the pot experiment result also displayed the low toxicity to plants. This work enriched the research system of ecological restoration in mining areas and provides a new strategy for the recycling of municipal sludge.
