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
This study presents a new compact single-layer microstrip 4-port super UWB MIMO antenna designed to operate in the frequency range of (2.5-50) GHz, achieving an impressive 320.2% impedance bandwidth. The antenna is based on a unique d-shaped geometry, specially tailored for applications in satellite communication, 5G, and Beyond, covering various bands including S-, C-, 4G LTE, sub-6 GHz, UWB, and X, ka-, k-, and ku- satellite communication bands. This aligns with Europe's efforts to harmonize by designating the 26 GHz band as a pioneer band for 5G. Additionally, 5G millimeter-wave frequencies are increasingly used in Internet of Things (IoT) applications and industrial automation. In the 5G spectrum, the midband (FR1) spans 1 GHz to 7 GHz, while the high band (FR2) covers frequencies from 24 to 52 GHz and smart wearable devices, vehicle radars, satellite communications, and smart 5G remote sensors devices. The antenna system comprises four orthogonally symmetrically placed identical radiating elements, each featuring a d-shaped patch. The metallic ground plane incorporates a curvature with a simple half-circle shape, effectively enhancing the antenna's matched bandwidth by altering the current distribution, consequently affecting the inductance and capacitance within the ground plane. A MIMO structure comprising four elements of the proposed antenna is introduced. Both simulation and experiments of the MIMO system demonstrate the antenna's impressive performance, showcasing an impedance bandwidth of 2.5 to 50 GHz, a whole-working bandwidth isolation exceeding 20 dB, an envelope correlation coefficient (ECC) below 0.013, and a significant increase in diversity gain (DG) of over 9.98 dBi. The antenna exhibits excellent radiation characteristics and a stable gain, making it highly suitable for UWB MIMO system applications.
