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
Congo Red (CR) dye is classified as a toxic and carcinogenic substance, posing significant health and environmental risks. To address this issue, the adsorption efficiency of CR on natural bentonite and hydroxyapatite (HA) was systematically studied. The adsorbents were successfully characterized by XRD, FTIR, and SEM analysis. Optimization through the Box-Behnken method identified the optimal conditions (pH = 6.5, initial dye concentration = 150 mg/L, and adsorbent mass = 1.5 g/L), resulting in maximum removal of CR of 95 % for HA and 84 % for bentonite. 2.6.2. Monte Carlo (MC) simulations provided insights into the spontaneous and favorable adsorption behavior, particularly under acidic conditions, driven by van der Waals interactions. Kinetic studies revealed that the adsorption followed a pseudo-second-order model (R
