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

We report here two new approaches for the chemical recycling/upcycling of nitrile butadiene rubber (NBR) to make either polyamines or polyols. Both processes are achieved through ruthenium-catalyzed hydrogenation reactions, where the chemoselective reduction of nitriles leads to the formation of either amines or alcohols. The hydrogenation of NBR to polyamines could be achieved at temperatures as low as 35°C, whereas a higher temperature (150°C) was required for the formation of polyols with catalytic turnover numbers reaching up to 2000. Additionally, polyamines were demonstrated for their potential application in CO
