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 introduces a compact ultra-wideband (UWB) monopole antenna featuring adjustable multi-band rejection capabilities while considering the influence of a human body model on stop bands to optimize bandwidth performance. By incorporating two L-shaped slots into the ground plane, the antenna achieves an extensive bandwidth of up to 140% (3-17 GHz). The adjustable triple-band rejection at 4.3 GHz, 5.6 GHz, and 6.5 GHz is realized through the integration of two PIN diodes within a modified W-shaped slit, two Γ-shaped slits with PIN diodes on the radiating patch, and a T-shaped stub on the ground plane. With its compact dimensions (18 mm × 12 mm × 0.8 mm), the antenna provides broad impedance bandwidth, cost-efficient fabrication, suitability for in-body microwave applications, and omnidirectional radiation characteristics in the H-plane. The prototype's performance is evaluated based on VSWR and radiation pattern analysis, demonstrating that the proposed adjustable antenna is well-suited for various UWB applications.
