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

Mobilization and release of arsenic (As) from the soil matrix is essential to promote the in situ remediation efficiency of As-contaminated soil. In the current study, two aerobic As(V)-reducing strains Leclercia sp. SMR8 and Klebsiella sp. SMR14 were isolated from As-contaminated soils. The As(V) reduction capacity was mediated by the arsC gene which was successfully amplified from both strains. The bacterial growth characteristics were evaluated, and both strains demonstrated good environmental adaptability with high As(V) tolerance, wide growth temperature range, and utilization of various carbon substrates. Except for bacterial growth and regulation of ars genes, initial As(V) concentration was confirmed as the dominant factor impacting the As(V) reduction rate by the strains. The reduced As(V) proportion decreased from 95 to 70% with increasing the initial As(V) concentration from 100 to 600 mg/L. The results of soil extraction experiments showed that the addition of the strains promoted As extraction efficiency from contaminated soil, and the process was significantly influenced by the added carbon substrates. SMR14 using glucose as a carbon source exhibited excellent extraction efficiency, indicating application potential in soil remediation.
