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

This paper presents a novel deployable antenna design with reconfigurable radiation patterns suitable for various indoor Internet of Things (IoT) applications. Inspired by origami, the antenna comprises a central monopole patch housed on a magic cube (MC-2) and two other modular units comprising stacks of magic cubes (MCs). In compact form, i.e., State-1, the antenna occupies a space of 50 mm, whereas in other states, it occupies a maximum of 150 mm space. Pattern reconfigurability is achieved by simply folding or unfolding these units. The antenna operates in four different states. For example, when both MC-1 and MC-3 are folded, the antenna exhibits an omnidirectional pattern (State-1). When either MC-1 or 3 are folded, the antenna shows directional behavior (States 2 and 3), offering ± 90° beam switching, whereas when both MC-1 and 3 are unfolded, the antenna exhibits bidirectional behavior (State 4), directing the main beam toward 88° and 92°. The antenna operates in the 2 GHz band and exhibits peak gains ranging from 2 dBi to 9 dBi. The excellent agreement between the simulated and measured results validates the design. This cost-effective, reconfigurable antenna presents a promising solution for diverse indoor IoT applications because of its cost-effectiveness and reconfigurable nature.
