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

Red-light-driven atom transfer radical polymerization (ATRP) using methylene blue as a photocatalyst has attracted considerable attention due to its high efficiency and oxygen tolerance. However, its application to functional polymers remains unexplored. Here we demonstrate the synthesis of liquid-crystalline polymers (LCPs) under ambient conditions using red-light-driven ATRP. Well-controlled polymerizations with high monomer conversions were achieved within several hours. The polymer growth could be precisely regulated by alternating the light irradiation on and off. Molecular weights were tuned by adjusting the polymerization conditions, affording LCPs with narrow molecular weight distributions. A clear relationship between molecular weight and LC behavior was observed. The method was extended to various mesogenic monomers and polymerizable groups, confirming its broad applicability. Moreover, controlled polymerization was achieved using accessible light sources such as sunlight and smartphone LED flashlights. This versatile approach enables efficient LCP synthesis and facilitates exploration of structure-property relationships in functional soft materials.
