A metasurface-enabled green-smart window for intelligent wireless communications with high visible transparency and low infrared emissivity.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
New-generation windows require advanced multi-physics modulation capability to accommodate diverse functions, including optical transparency, thermal insulation, and wireless communication compatibility. In response to these demands, metasurfaces have emerged as a promising solution owing to their versatile and energy-efficient electromagnetic (EM) wave manipulations. However, the existing prototypes suffer from fixed functionalities and limited intelligence, restricting their practicality and sustainability. Here, we show a green-smart window based on programmable metasurface to simultaneously achieve high visible transparency, low infrared (IR) emissivity, and reconfigurable EM responses. By integrating a compact RFID (radio frequency identification) tag, three intelligent functions are remotely reconfigured in a self-powering manner: EM transmission enhancement, selective EM shielding, and polarization filtering. For verification, a prototype is fabricated to validate its visible-IR-EM multi-physics controls, remote-sensing range, self-powering capability, and thermal management. Indoor-to-indoor (I2I) and outdoor-to-indoor (O2I) communication scenarios are established, demonstrating significant improvement in communication quality by using the green-smart window.
