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
Additively manufactured mechanical metamaterials exhibit extraordinary physical and mechanical performance. However, achieving a balance between lightweight design, strength, and energy absorption remains challenging. Here, we develop a material-structure-function integrated strategy to additively manufacture lightweight metamaterials. Specifically, strong yet ductile aluminum (Al) alloy with heterogeneous grain was developed to print hero shrew-inspired damage-resistant metamaterials. The synergistic interplay between microscale strengthening and mesoscale architectural stress regulation leads to a cross-scale coordination mechanism, which effectively bridges material heterogeneities and structural hierarchy for multilevel energy dissipation. Such a strategy enables our metamaterials to maintain a stable stress platform during deformation. Hence, our metamaterials display an excellent combination of ultralightweight (0.91 ± 0.01 g/cm
