Controlled hierarchical self-assembly of hyperbolic paraboloid molecules into two-dimensional superstructures with second-harmonic generation characteristic.
Article in Nature communications, 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
Hyperbolic paraboloid molecules, as systems with remarkable negative Gaussian curvature, have garnered considerable attention in chemistry and materials science due to their unique physicochemical properties. However, controlled organization of these curvature building blocks into well-defined superstructures remains challenging, primarily attributed to the constraints of their inherently contorted structures. Herein, we report the successful formation of hyperbolic-paraboloid-based crystalline two-dimensional (2D) superstructures in a controlled hierarchical manner. Employing a rigid yet flexible molecular design strategy, we guide the hyperbolic-paraboloid molecules through hierarchical self-assembly method from dimers to one-dimensional (1D) supramolecular columns and ultimately to 2D superstructures. Remarkably, these 2D superstructures exhibit strong second harmonic generation (SHG) with excellent polarization dependence. The strongest SHG signals were recorded at 1.5 × 10
