Measurement of a Preresonant Hyper-Raman Hyperpolarizability.
Article in The journal of physical chemistry letters, 2026. 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
Four wave mixing (FWM) spectroscopy is used to measure a preresonant hyper-Raman hyperpolarizability. The four wave mixing process known as hyper-difference frequency generation (HDFG), which depends upon the hyper-Raman hyperpolarizability, can be measured simultaneously with other well-studied four-wave mixing processes, which serve as an internal standard. We use coherent anti-Stokes Raman (CARS) response from deuterobenzene to quantify the acetonitrile ν(CN) hyper-Raman hyperpolarizability. This internal standard method is applicable to any infrared active vibration and greatly diminishes the barriers to quantification of hyper-Raman hyperpolarizabilities.
