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
The current study demonstrates a dual and wideband mmWave 4 × 4 port MIMO antenna for 5G and beyond applications. The proposed antenna is derived from a traditional inset-fed rectangular geometry, modified with multiple curved edges on the top plane to produce a large effective aperture and enable significant surface current distribution. Partial ground planes are connected using 45° tilted conducting strips to form a common ground, which enhances surface current distribution and balances power through each port. The antenna exhibits wide bandwidths of 2.3-6.5 GHz at resonant frequencies of 28-38 GHz, respectively. Moreover, the suggested antenna yields more than 21 dB isolation, 8.3 dB peak gain, 92% radiation efficiency, 89% multiplexing efficiency, an ECC of 0.00007, and a channel capacity of 21 bit/s/Hz. To validate the antenna design, the prototype was fabricated on a Rogers RT/Duroid 5880™ substrate, tested, and compared with simulated results, showing good agreement.
