Study of novel 3D-Printed auxetic metamaterial structures under compressive loading: design, simulation, and experiment.
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
In this study, three types of metamaterial cells, including honeycomb, cubic, and tetrachiral, were selected based on their high performance under compression test. Then, different arrangements of these cells created four new metamaterial structures named HT, HC, TC, and HTC. Because the aim of this research is to maximize specific energy absorption (SEA), cells were chosen based on their mechanical properties. After that, the structures were manufactured with a 3D printer, and compression tests were performed on them. Results showed that the HT structure had the highest SEA, followed by HTC, HC, and TC. Moreover, these structures have a higher SEA than solid specimens and many other metamaterial structures. In addition, all of them had negative Poisson's ratios between - 1 and - 1.7.
