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 investigates the optimization of multigravity separator (MGS) parameters for the beneficiation of specularite ore, using both Box-Behnken design (BBD) and central composite design (CCD) as response surface methodologies. The effects of the drum speed, wash water amount, and drum slope on the grade and recovery of specularite were evaluated. Results indicated that increased wash water and drum slope generally enhanced the Fe grade, while higher drum speeds had adverse effects. Conversely, recovery was maximized with lower wash water amounts, lower drum slopes, and higher drum speeds. The comparison between BBD and CCD designs revealed that both methods provided similar optimal grade and recovery values, though with different parameter settings. CCD demonstrated superior predictive performance with higher
