Spatial Coherence Structure-Mediated Transmission of Encrypted Three-Dimensional Objects and Hidden Information.
Article in Annals of the New York Academy of Sciences, 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
The development of three-dimensional (3D) information encryption and transmission is constrained by the massive data bandwidth involved and the inherent limits of first-order optical parameters. Here, we present a novel scheme that integrates the spatial coherence structure of the optical field with holographic coding to enable secure transmission of encrypted 3D objects and concealed information. By exploiting the second-order coherence of partially coherent light, 3D information is encoded into the spatial coherence structure. Joint transmission is then achieved through two-dimensional (2D) intensity information. Meanwhile, the inherent concealment of the spatial coherence structure enables the synchronous transmission of hidden information. The incorporation of hidden information enhances system security, ensures transmission integrity, and facilitates the detection of degradation, loss, or tampering. This method achieves both efficient encrypted transmission and high-fidelity 3D reconstruction, markedly enhancing physical-layer security and resistance to attacks. This work provides a coherence structure-based framework for secure and efficient transmission of 3D data.
