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

Polymers with a cyclic architecture are invaluable constructs for a variety of materials science and engineering applications. Due to their macrocyclic nature, these plastics are imbued with enhanced mechanical durability; a single scission event along the backbone keeps the polymer intact, and the molar mass remains unchanged. Hence, polymer topology can be envisioned as a strategy to prolong the useful lifetime of a material before failure. With a growing interest in synthesizing such cyclic polymers using ring-expansion metathesis polymerization (REMP), there remains an unmet need to further understand the structure-activity relationships of the requisite organometallic initiators. While analogous Ru-based initiators for ring-opening metathesis polymerization (ROMP) have been widely studied, this same focus has not been applied to REMP. Herein, we report the synthesis and activity of
