1 · What the graph read from it

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.

2 · The registry

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

To evade ultrasonic predation by bats, moths have evolved wing scale architectures capable of absorbing and scattering high-frequency acoustic signals. Drawing inspiration from this natural defense strategy, a bioinspired multifunctional metamaterial is presented that integrates broadband sound absorption, thermal insulation, and mechanical energy dissipation within a unified structural framework. Inspired by the graded pore architecture of moth scales, acoustic performance is first optimized via genetic algorithm-driven pore design and the structures using 3D printing. The resulting metamaterial exhibits broadband acoustic absorption with an average coefficient of 0.742 across the 1000-6000 Hz frequency range. When implemented in helmet-based noise reduction systems, the proposed metamaterial outperforms conventional commercial foams in suppressing environmental noise. In addition, the metamaterial retains a negative Poisson's ratio under large deformation, which enhances its mechanical energy dissipation and impact resilience. Furthermore, the alternating architecture of polymer layers and internal air cavities reduces the effective thermal conductivity to 30.2 mW m
