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

Facing global energy and environmental challenges, transportation industries are adopting lightweighting as a key strategy to improve energy efficiency. Nylon12 is a crucial material in lightweight applications. However, 1,5,9-cyclododecatriene (1,5,9-CDT) serves as a key intermediate in its synthesis, and the preparation methods of 1,5,9-CDT currently still suffer from low catalytic activity and insufficient conversion, coupled with a lack of mechanistic studies on macrocyclic formation. To address these challenges, this study focuses on the key synthesis technology of 1,5,9-CDT by designing and preparing four novel nitrogen-ligand-supported transition metal catalysts (Cat.1-Cat.4). Using 1,3-butadiene as the monomer, the effects of the catalyst performance and reaction conditions on the oligomerization process were systematically investigated. These results demonstrate that Cat.2, under optimized conditions (toluene as solvent, catalyst content of 0.2 g/L in polymerization solution, polymerization temperature of 50 °C, and
