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

Liesegang patterns are self-organized macroscopic structures formed by precipitates. Traditional methods for producing these patterns rely on gel phases, which inhibit flow but introduce complications, such as undesired chemical interactions. This study presents a strategic approach utilizing a "Hele-Shaw cell", consisting of two glass plates that create a narrow gap (30-225 μm). This setup prevents flow due to friction between glass surfaces without the use of a gel. We identified two critical thresholds for the gap thickness: one that inhibits flow and another that facilitates discrete precipitate bands. For aqueous solutions of CuCl
