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
Nondiffracting beams have gained significant interest because of their ability to propagate over long distances without divergence, making them highly valuable in various laser applications. Historically, laser sources for nondiffracting beams were constrained by their symmetry in the cavity's coordinate system and intracavity elements, which restricted the types of beams that could be directly generated from the cavity. This study presents the first direct generation of nondiffracting Parabolic-Gauss beams, as well as other Helmholtz-Gauss beams with helical wavefronts, directly from a laser cavity. The key technique involves controlling the two end-phase boundaries of a dual-modulation digital laser resonator with a concentric configuration, thereby ensuring stable round-trip conditions for generating various nondiffracting beams. The experimental results demonstrated that the dual-phase modulation digital laser could generate Parabolic-Gauss, Bessel-Gauss, Mathieu-Gauss beams, and even vortex nondiffracting beams. This laser source enables dynamic, real-time adjustment of beam properties, which is highly beneficial for applications requiring nondiffracting beams.
