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
Tetracycline (TC) is not easy to degrade in human or animal and can even be converted to more toxic substances. The overuse and wanton discharge of TC also caused serious problem of water pollution. This study investigated the removal of TC by biochar (BC) prepared from waste Auricularia auricula dregs and modified with NaOH by characterizing the pH and adsorption kinetics, and using isotherm models. Three BC samples were prepared and that produced using the highest concentration of NaOH (8 M) was more suitable for removing TC, where the adsorption amount was 26.65 mg/g. Pseudo-second order and Freundlich models both fitted well to the adsorption kinetics, and diffusion of the liquid film was considered the rate-controlling step. The multivariate mechanism involved electron interplay, H-bonding, and π-π electron donor-acceptor interactions. The results of this work can not only make the waste Auricularia auricula dregs resourceful, but also provide a new method for the removal of TC in wastewater, which is of great practical significance.
