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

Terahertz (THz) absorbers with broad bandwidth and high absorption are significant interest for applications in electromagnetic shielding and photonic devices. In this work, we propose a broadband THz metamaterial absorber consists of square-pyramid structure with optical transmittance, composed of liquid water, polyethylene terephthalate, and indium tin oxide. The continuously varying square-pyramid configuration promotes multiple reflections and electromagnetic field superposition, in combination with the strong intrinsic THz absorption of water, which leads to efficient THz absorption. As a result, the proposed absorber achieves absorption exceeding 90% from 0.5 to 10 THz, over 95% from 0.65 THz to 10 THz, and over 99% from 1.2 THz to 10 THz. In addition, the absorber exhibits polarization-insensitive behavior and maintains a broadband absorption bandwidth of 7 THz with absorptance above 90% for incident angles up to 70°. These features highlight the proposed design as a promising platform for broadband THz absorption in practical applications where visible-band optical transmittance is desirable.
