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

Chemical upcycling of waste plastics can play an important role in developing greater circularity in the material flows associated with the plastics industries. In this study, a fundamental understanding of upcycling poly(ethylene terephthalate) (PET) using ammonolysis is established. First, rate constants are determined for model studies of the ammonolysis of dimethyl terephthalate (DMT) in methanol. Ammonolysis proceeds sequentially, and a first ester group of DMT reacts with ammonia to produce methanol and the monoamide methyl 4-carbamoylbenzoate (MCB). Next, MCB reacts with ammonia to yield methanol and terephthalamide (TPD). At 100 °C, the pseudo first order rate constants are
