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

Rapid advances in the Internet of Everything (IoE) drive microwave wireless power transfer (MWPT) technology for charging wireless smart devices. However, environmental obstacles and safety concerns associated with high-power transmission present new challenges for the technology. To address these problems, an amplitude-dependent caustic metasurface (ADCMs) design method is proposed for generating self-bending radio frequency circular Airy beams (RFCAB). The self-accelerating circular Airy beam has a natural hollow region, providing an obstacle avoidance and safety zone during microwave transmission focusing. The ADCMs, derived from caustic theory, are capable of generating RFCAB with arbitrary curvatures and offer flexible control over the positioning of the energy focus. An innovative feed architecture, a uniform circular array (UCA) emitting vortex electromagnetic waves, is used to match the amplitude excitation on which the metasurface depends. The designed ADCMs consists of 1/3 wavelength units and contains only two layers of substrate, with high transmittance and full 360
