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

The production of light olefins from polyethylene (PE) has significant industrial potential. Zeolites have been widely used in petroleum refining for their ability to cleave C-C/C-H bonds and facilitate light olefins selectivity, thanks to their adjustable acidity and pore structure. However, the interaction between zeolites and conventional hydrocarbons or polymer reactants is quite different, a distinction frequently overlooked but has great influence on their reaction. Based on this, we describe a PE self-confined cracking mechanism that can produce C
