Effect of THz spectra of L-Arginine molecules by the combination of water molecules.
Article in iScience, 2022. 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
Most biomolecules are biologically active only in water; hence, it is worth investigating whether THz spectra of biomolecules are affected by the combination of water molecules and biomolecules. In this report, by combining the sample cell with the THz-TDS system, the THz spectra of L-Arginine crystal as well as its hydrate and aqueous solution are measured. The experimental results show that L-Arginine crystal and its hydrate share the same three absorption peaks at 0.99, 1.46, and 1.7 THz, respectively. But the trend of characteristic absorption spectrum of L-arginine solution is almost identical to that of free water. Because the contents of free water and hydrated water are different in many diseased and normal tissues, the diseased tissues can be detected according to the difference in THz spectral information. The proposed approach provides a reliable means for the detection of pathological changes of active molecules and tissues.
