The role of unidirectional surface roughness on the regularity of LIPSS generated on stainless steel using femtosecond lasers.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Laser induced periodic surface structures (LIPSS) are directional and periodic nanostructures generated in most materials when irradiated with linear polarized laser beams under certain irradiation conditions. LIPSS present a wide range of well-known properties and applications, but their implementation on the optical field is restricted because of their low regularity in comparison to microstructures fabricated by other methods. Surface roughness has an impact on LIPSS regularity, as it can promote their generation acting as a seed or influence their orientation in favor of the roughness direction. During this study, the influence of the surface roughness and its orientation on the LIPSS regularity has been explored by means of DLOA (dispersion of the LIPSS orientation angle), for stainless steel with arithmetic mean height (Sa) parameter ranging from a few nanometers to one micrometer. The experimental results have proven that the magnitude and a preferred direction of substrate roughness affect the coherence and orientation of the LIPSS.
