1 · What the graph read from it

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.

2 · The registry

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 paper, a microstrip diplexer with a very compact size is presented for 5G networks. The proposed diplexer operates at 3.5 GHz and 4.2 GHz, which fall within the 5G extended C-band (3.3-4.2 GHz) allocation, showing potential for next generation wireless applications. The design of this diplexer utilizes two similar filters with different sizes. In designing the filters, T-shaped resonators, meandered lines, and coupled lines are used to form a novel structure called the modified T-shaped step-impedance resonator (MTSIR). The proposed diplexer employs two modified T-shaped step-impedance resonators (MTSIRs) to achieve compact size, low insertion loss, and high isolation in the 5G extended C-band, while maintaining a very low frequency ratio of 1.2. The proposed diplexer operates at a frequency of 3.5 GHz with an insertion loss of 0.5 dB. The second channel of the diplexer operates at a frequency of 4.2 GHz with an insertion loss of 0.8 dB. The designed diplexer features a very compact size of 18.2 mm × 10.9 mm, corresponding to a normalized size of 0.16 λg × 0.28 λg.
