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 presents a sustainable approach utilizing activated carbon derived from hazelnut shells as an adsorbent for the simultaneous quantitative analysis of 48 different volatile organic compounds (VOCs) via GC-MS. The surface area of the produced activated carbon was successfully enhanced through the concurrent application of heat and steam. The effect of critical parameters, such as particle size and steam ratio, on the surface area and product yield was investigated. A high steam ratio was observed to increase the total surface area while decreasing the micropore surface area, which is attributed to the conversion of micropores into larger mesopores. Consequently, a 0.240-0.125 mm particle size and a 1.0 steam/AC ratio were selected, as they provided an optimal balance between back pressure and surface area. The method achieved exceptionally low limits of detection (LOD), with the lowest value of 3.72 µgm⁻
