Modulation of trace element bioavailability for two earthworm species after biochar amendment into a contaminated technosol.

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.
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
Biochars are used as amendments to improve soil quality, but their effects on edaphic organisms such as earthworms remain controversial. This study aimed to assess the effects of adding a poultry manure-derived biochar into a contaminated technosol on trace element (TE) (i.e. As, Cd, Cu, Pb, and Zn) bioavailability for two earthworm species, Aporrectodea icterica and Aporrectodea longa. Three components of the bioavailability concept were determined using a pot experiment: (1) total soil TE (potentially reactive) and TE concentrations in the soil pore water (environmental availability), (2) TE concentrations in depurated whole earthworm bodies (environmental bioavailability) and (3) ecophysiological and biochemical effects on earthworms (toxicological bioavailability). Biochar addition increased TE concentrations in the soil pore water respectively from 1.8, 2.7, 9.4, 0.7 and 959 to 6, 6.2, 19.3, 6.9, and 3003 µg L
