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

Symmetry is known to strongly influence the course of a chemical reaction. It has also been found to play a key role in vibrational strong coupling (VSC), where it can influence the outcome of chemical reactions or alter chemical equilibria. However, the precise nature of this effect and its extent remains elusive. To further explore the role of vibrational symmetry, we have investigated the equilibrium constants of different charge transfer complexes, in particular of isomers of trimethyl benzene belonging to different point groups from which a general symmetry rule emerges. We describe the strongly coupled system by a direct product of irreducible representations associated with the complexes and the cavity. As a consequence, the coupled vibration is associated with a new irreducible representation that projects differently on the reaction coordinate of the charge transfer complexation, reflecting the changes in the equilibrium constants. This phenomenological symmetry rule points to a general underlying framework for predicting the outcome of chemical reactivity under VSC.
