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 research paper presents a novel high-gain, wideband metamaterial (MTM)-based antenna designed for 5G millimeter-wave (mm-wave) applications. The antenna features a dual-band H-shaped patch radiator printed on a 15 mm × 15 mm Rogers 5880 substrate, backed by a metallic ground plane with a square aperture. A 2 × 2 MTM superstrate layer is positioned 6.1 mm above the patch antenna to improve gain and bandwidth. The MTM layer, fabricated on a 0.2 mm Rogers 4003 C substrate, incorporates H-shaped metallic patterns on the top surface and circular resonators on the bottom. Simulated effective constitutive parameters confirm negative permittivity (ɛ), negative permeability (μ), and negative refractive index (n) within the target frequency range, validating the metamaterial properties. The S-parameters derived from the equivalent circuit model developed in ADS closely match those obtained from the CST simulations. Characteristic Mode Analysis (CMA) is conducted to examine the resonance behavior of the proposed MTM-based antenna. The experimental results demonstrate the wideband and high-gain performance of the proposed antenna, featuring an impedance bandwidth of 4.8 GHz, peak gains of 11.4 dBi at 30 GHz and 9.19 dBi at 27.4 GHz, and a radiation efficiency of 95% across the entire operating frequency band.
