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

Diffractive security images, constructed with micro-nano structures, are widely used in anti-counterfeiting due to their inherent high spatial frequency resolution and dynamic color variation. However, traditional diffraction anti-counterfeiting labels (DALs), typically based on acrylic ester materials, are susceptible to counterfeiting due to their simple encryption structures and the limited information capacity of single-channel encryption. Furthermore, in harsh environments such as high temperature or high humidity, they are prone to deformation, which can lead to loss of verification functionality. To address these limitations, we propose constructing eight high-resolution, angular-switchable, independent diffraction images on photosensitive polyurethane (Pho-PU) films through buckling structures that reveal different encrypted images as the viewing angle changes, through sample rotation, or varied illumination. We discuss the designability and controllability of periodic buckling structures and demonstrate how common information and secret keys can be integrated through this angle-multiplexing strategy. This systematic approach to multi-image encryption based on buckling structures provides an effective alternative for fabricating high-security DALs.
