Chiroptical Signal Amplification in Amorphous Siloxane Network by Asymmetric Ring Distortion.
Article in Journal of the American Chemical Society, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Understanding the polymorphs and amorphous structures of silicon oxide is an essential issue not only for fundamental science but also for energy and environmental science. In particular, the amplification mechanism of chiroptical signals in amorphous silicon oxide has drawn significant attention. Here, we explore how the chiroptical signal can be amplified in amorphous silicon oxide (silica) having nanoscale helical structures. Our findings reveal that the observed vibrational circular dichroism (VCD) signals originate from the formation of symmetry-broken siloxane ring structures. Furthermore, we demonstrate that the amplification of siloxane VCD signals is driven by an enthalpy-driven asymmetric ring distortion during volumetric shrinkage.
