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

Depolymerization is a key pathway in the transition to polymer circularity. By breaking down polymers into their original (or new) building blocks to create new products, the polymer "cycle" can be closed. However, polyvinyl chloride (PVC), a ubiquitous thermoplastic, has been largely absent from research in depolymerization, although it has some unique advantages compared to other commodity vinyl polymers. Here, we present methods for depolymerizing PVC via ozonolysis, a well-established and practiced method for the oxidative cleavage of alkenes. By intentionally introducing sequences of conjugated C═C bonds to produce dehydrochlorinated PVC (DHPVC), the sites are introduced into the polymer backbone that are readily cleaved by ozone (O
