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

Polythioureas with great potential in precious metal recovery materials, dielectric materials, light refractive materials, self-healing materials, and adhesives have become a group of popular polymer materials. While various synthetic approaches have been reported for different polythiourea structures, which generally involve expensive and toxic monomers, several polythiourea structures, such as asymmetric aromatic polythioureas, still have limited access. Herein, a base-catalyzed multicomponent polymerization (MCP) of elemental sulfur, diisocyanides, and diamines was developed, which was generally applicable for both aromatic amines with low reactivity and aliphatic amines with high nucleophilicity, affording polythioureas with great structural diversity, high
