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
In this research work, the desorption of malachite green dye from water by means of adsorption onto NaOH-activated carbon obtained from agricultural waste sources including coconut husks and peanut shells is examined. Scanning Electron Microscopy, X-Ray Diffraction, and Fourier Transform Infrared Spectroscopy were applied for activated coconut husk carbon and activated groundnut shell carbon. The activated coconut husk carbon demonstrated a remarkable removal efficiency of 95.6%, whereas the activated groundnut shell carbon exhibited a removal efficiency of 92.1% at an optimal pH of 7-8, adsorbent dosage of 0.03 g, and initial dye concentration of 20 ppm. The adsorption mechanism followed the Freundlich isotherm model with an R
