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

Mechanochemical depolymerization in a ball mill can be used to convert poly(styrene) (PS) into monomeric styrene under milder conditions than thermal depolymerization. Continuous sampling of product flows shows that the rate of styrene formation increases significantly when PS powder is converted into a cohesive state, a viscous, continuous material phase that tends to coat the grinding spheres, once the temperature of the grinding surfaces approaches the PS glass transition temperature (~100°C). This enhancement is attributed to intensified mechanical shear stresses that generate favorable reaction environments for depropagation of chain-end radicals in the bulk of the cohesive state. The faster depropagation steps also increase the selectivity of styrene relative to byproducts, such as methane, benzene, toluene, and ethylbenzene.
