Biochar derived from corn stalk and polyethylene co-pyrolysis: characterization and Pb(ii) removal potential.
Article in RSC advances, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Biochar is widely used as adsorbents for gaseous or liquid pollutants due to its special pore structure. Previous studies have shown that the adsorption performance of untreated biomass pyrolysis crude carbon is poor, which can be improved by optimizing physicochemical properties such as pore structure and surface area. The study focused on the co-pyrolysis of skins, pith, and leaves with polyethylene and potassium hydroxide modification to adjust the quality of the biochar, compared with raw materials of corn stalks without separation. The physical and chemical properties of the biochar were analyzed and the adsorption effect, adsorption isotherms, and kinetics of Pb(ii) removal were investigated. Results demonstrated that co-pyrolysis of biomass and polyethylene increase the yield of biochar with an average increase of about 20%. Polyethylene brought high aromaticity, high calorific value and stable material structure to biochar. Potassium hydroxide modification increased its specific surface area and made the pore structure of biochar more uniform, mainly microporous structure. The specific surface areas of the four modified biochar were 521.07 m
