Piezoelectricity from Dopant-Induced Structural Distortions in Molecular Crystals Revealed by Raman Spectroscopy.

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
Crystal engineering offers a route to functional molecular solids through controlled noncovalent interactions. In centrosymmetric crystals, piezoelectricity can be induced by stereoselective doping, where chiral additives are incorporated in a biased orientation that lowers inversion symmetry and generates net polarization. However, the microscopic origin of this polarization, specifically whether it arises primarily from dipole mismatch between the dopant and the host molecule it replaces, or from dopant-induced lattice distortion, remains generally unclear. Here, we disentangle these two contributions by incorporating four chiral
