1 · What the graph read from it

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.

2 · The registry

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

Chitosan has significant advantages due to its good biocompatibility and biodegradability. However, the original chitosan often has problems such as limited adsorption capacity and poor selectivity. Therefore, modifying chitosan to improve its adsorption performance has become an important research direction. This study adopted molecular dynamics simulations to explore the factors influencing the physical modification of chitosan and further conducted adsorption experiments with three different dyes. The results indicated that when combined with different clays, the interaction between chitosan and montmorillonite was more likely to occur, making it a suitable adsorbent for physical modification. As the molecular weight (MW) of chitosan increased, the <500 MW chitosan-modified bentonite exhibited the maximum adsorption capacity for different dyes, with the adsorption rates of 90.73% (methylene blue), 72.05% (methylene orange), and 32.28% (cresol red) at 20 mg/L, respectively. The adsorption kinetic and thermodynamic analysis indicated that the adsorption process is consistent with the pseudo-second-order kinetic model (R
