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
Spiral optics have been proposed to extend depth of focus through controlled phase modulation. We characterized the RayOne Galaxy spiral intraocular lens using high-resolution Mach-Zehnder interferometry and a simulated pseudophakic Arizona eye model. Wavefronts were decomposed into Zernike polynomials and compared with monofocal, trifocal, and spherical-aberration-based extended-depth-of-focus (EDOF) lenses. The Galaxy exhibited a smooth EDOF profile with a moderate reduction in contrast rendering. Symmetry analysis showed that radially symmetric aberrations primarily generated the EDOF effect, while the spiral component played a secondary role.
