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
In this work, a compact dual-band frequency selective surface (FSS) for path-loss and coverage improvement in advanced wireless communication is showcased. The proposed FSS is a single-layer design with stable and high performance at both 24 GHz and 38 GHz operating frequencies, respectively. The design is highly compact with two wide-band reflection coefficient responses having 49.5% (14.5-26.4 GHz) and 66.57% (35.8-39.8 GHz) bandwidth respectively. To the best of the author's knowledge, the proposed structure is the most compact design reported thus far with [Formula: see text] electrical length at the lower cutoff frequency. With the proposed design architecture, it is easy to reconfigure the FSS. The small size of [Formula: see text] enables effective operation in different communication environments. For coverage improvement and experimental validation, a [Formula: see text] element array of the total footprint of [Formula: see text] is fabricated and measured. The measured results demonstrate a significant coverage enhancement of up to 35 dB, for the Ku band, N257, and N260 millimeter wave (mm-wave) 5G bands. The proposed design is useful to enhance 5G mm-wave communication by tackling the fading effects or the presence of obstacles.
