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 ring-opening copolymerization of propene oxide and carbon dioxide is an effective route to make polycarbonates. Catalysts showing high activities, high polymer selectivities, molecular weight control, and tolerance to impurities are rare. Here, a series of four Co-(III)-Na-(I) catalysts are tested for the ring-opening copolymerization of propene oxide and carbon dioxide. The complexes have systematic variations in the ligand structure in which both Co-(III) and Na-(I) binding sites are modified. Significant differences in catalyst performance are observed, with the lead catalyst featuring six oxygen donors and an ethylene diamine linker. This catalyst shows excellent activity and high poly-(propene carbonate) selectivity at elevated temperatures (TOF = 1428 h
