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

Despite its ubiquity, scalable recycling of poly(vinyl chloride) (PVC) remains elusive. One challenge is that the waste streams can be contaminated with plasticizers. Herein, we present a strategy that repurposes these plasticizers as redox mediators in a controlled-voltage electrolysis to dechlorinate PVC. Five common plasticizers were evaluated as redox mediators. In addition, using voltage limits via a galvanostatic cycling with potential limitation protocol attenuated deleterious mediator decomposition. Among the plasticizers screened, trioctyl trimellitate enabled up to 97% dechlorination of PVC across a range of PVC samples, including commercial-grade rigid pipe and flexible tubing, and scales (up to 0.5 g), illustrating broad applicability. This method achieves near-quantitative PVC dechlorination in a simple, one-pot transformation while simultaneously utilizing the liberated chloride, offering a promising solution for transforming waste PVC into recycled products.
