1 · What the graph read from it

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.

2 · The registry

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

Developing high-performance nonlinear optical materials that simultaneously deliver large effective nonlinearity and device-level integrability remains a longstanding challenge. Ferroelectric nematic liquid crystals (FNLC) have emerged as a promising platform owing to their intrinsic non-centrosymmetry, theoretically predicted large second-order nonlinearity, and solution processability on diverse substrates. However, realizing strong second-harmonic generation (SHG) in FNLCs has been hindered by pronounced orientational disorder inherent to fluidic systems without lattice constraints. Here, this limitation is overcome through a surface-anchoring strategy that induces highly ordered polar topological structures within self-assembled FNLC droplets. The resulting architecture yields a giant effective SHG coefficient of 56.9 pm/V-an order of magnitude higher than previously reported FNLC systems-together with SHG efficiency surpassing that of benchmark LiNbO
