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

Backscatter communication (BC) is a low-power technology that transmits data by reflecting ambient RF signals. Conventional BC, based on antenna impedance modulation, suffers from low data rates and poor interference resistance. Programmable information metasurface (IMS) offers a breakthrough by enabling precise wave control. This article presents a PIN-diode-based IMS for polarization-diversity backscatter transmission. It performs full-space secondary modulation, converting horizontally polarized incident waves into ±45° polarized signals. Operating at 5 GHz, the system uses two polarization channels with BPSK and BASK modulation to transmit the same data, achieving 2 Mbps with improved reliability through diversity. The proposed system exhibits low power consumption, strong interference resistance, and high stability, making it suitable for IoT applications such as smart healthcare and environmental monitoring.
