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
This study evaluated the effectiveness of regenerating WG-12 granular activated carbon used in drinking water treatment, based on a case study of the "Miedwie" Water Production Plant supplying the city of Szczecin, Poland. The investigation was conducted using samples collected from eight adsorption beds after five years of operation. Thermal regeneration was performed in a steam atmosphere at 600-850 °C for 20 min, and the regenerated samples were subsequently demineralized using a 1.75% HCl solution. The effectiveness of the process was evaluated using changes in the iodine number, BET specific surface area, bulk density, mechanical strength, regeneration mass yield, and an adsorption-mechanical trade-off index. Thermal regeneration substantially improved the adsorption properties of the spent carbon. The mean iodine number increased from 528.2 mg/g to 858.1 mg/g after regeneration at 800 °C, while the specific surface area increased from 480.4 to 806.9 m
