Disulfide Chromophores Arise from Stereoelectronic Effects.
Article in The journal of physical chemistry. B, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Bonds between sulfur atoms are prevalent in natural products, peptides, and proteins. Disulfide bonds have a distinct chromophore. The wavelength of their maximal absorbance varies widely, from 250 to 500 nm. Here, we demonstrate that this wavelength derives from stereoelectronic effects and is predictable using quantum chemistry. We also provide a sinusoidal equation, analogous to the Karplus equation, that relates the absorbance maximum and the C-S-S-C dihedral angle. These insights provide a facile means to characterize important attributes of disulfide bonds and to design disulfides with specified photophysical properties.
