Growth, physiological responses, and copper accumulation in seven willow species exposed to Cu-a hydroponic experiment.
Article in Environmental science and pollution research international, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
Selecting plant species, especially woody species, that can tolerate and accumulate high levels of heavy metals is crucial for the purpose of phytoremediation. In the present study, seven willow species/clones were evaluated for their variations in copper (Cu) tolerance, Cu accumulation, and their relative physiological responses, when exposed to different doses of Cu (control, 15, and 120 μM) in a hydroponic system for 40 days. Upon Cu exposure, all tested willow species/clones (Salix, S.) remained relative normal growth, albeit with some visual evidence of Cu toxicity observed. Seven willow species remained relative high total biomass with tolerance index > 0.6 when being exposed to 120 μM Cu, suggesting their high Cu tolerance. Exposure to 120 μM Cu resulted in notable declines (16.3-76.1%) in photosynthesis in all willow species. Increases in the soluble sugar content and decreases in the soluble protein content in the leaves of five willow species (S. integra "Yizhibi", S. jiangsuensis "J172", S. matsudana 14, S. matsudana 25, S. matsudana 89) were found in the 120 μM Cu treatment. The majority of Cu mainly accumulated in the roots, ranging from 1916 to 26,244 mg kg
