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 from different agrowastes has been extensively used to eliminate various pollutants from wastewater. In the present work, raw lemon peels (RLP) were activated by microwave irradiation then converted into activated biochar (RLP-BC) by pyrolysis. Afterwards, both RLP and RLP-BC have undergone microwave-assisted chemical modification by hydrogen peroxide and nicotinic acid. These biosorbents were denoted as RLP, RLP-BC, OH-LP, OH-LP-BC, N-LP, and N-LP-BC respectively. They were characterized using different analytical techniques including IR, SEM, and EDX to investigate their properties. Surface topography of selected sorbents was examined using AFM, and their BET data were provided. These biosorbents were then tested for their ability to remove Co(II) from aqueous solutions under varying conditions. The adsorption experiments showed that the modified lemon peel materials showed adsorption affinity for Co(II) ions in alkaline medium, and the highest removal efficiency was achieved at pH 9. The adsorption equilibrium of Co(II) onto the biosorbents was described by the Langmuir isotherm, while adsorption kinetics were modeled using a pseudo-second-order approach for RLP-BC, N-LP, and N-LP-BC adsorbents. Thermodynamic parameters were also assessed. Results indicated that chemically modified biochar was the most effective in Co(II) removal. OH-LP-BC exhibited the highest Q
