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

The development of advanced solar energy harvesting systems requires metamaterial absorbers that overcome the limitations of conventional noble-metal designs, particularly their insufficient thermal stability and significant optical losses. This study introduces a stepped-height concentric dual-ring metamaterial absorber (SHCDR-MA) based on titanium nitride (TiN), which achieves an average absorptivity of 99.27% across an ultra-broadband spectrum from 150 to 3000 nm. The structure employs a vertically graded dual-ring configuration, atop a silicon dioxide (SiO
