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
Integrated terahertz (THz) communication-sensing-computing systems require reconfigurable platforms that can simultaneously support logic operations and signal modulation. Here, we propose a subarray programmable THz metasurface that elevates the subarray to the minimum addressable unit. Within each subarray, a high electron mobility transistor (HEMT) serves as the active material; collective resonance tuning of the two-dimensional electron gas (2DEG) enables broadband control of array-level resonances and transmission amplitude. Using spatial domain combinatorial coding across subarrays, the device maps Boolean logic over a wide bandwidth and directly realizes four-level pulse amplitude modulation (PAM-4) at the wavefront. In a 220 GHz quasi-optical link, dynamic measurements demonstrate real-time Boolean functions up to 200 MHz and stable PAM-4, while a single-tone modulation reaches 6 GHz. This subarray-level gating strategy integrates optical logic and high-order amplitude modulation on the same hardware without increasing addressing complexity, providing a scalable route to compact, reconfigurable THz front ends for future communications and intelligent sensing.
