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

Microwave imaging (MWI) presents a promising, safer, more affordable, and portable alternative for detecting strokes compared to traditional methods, such as CT and MRI, which have limitations related to radiation exposure, cost, and accessibility. This paper focuses on the design and performance evaluation of a compact, T-shaped, two-port Multiple-Input Multiple-Output (MIMO) antenna, developed explicitly for microwave-based brain imaging. MWI operates by exploiting differences in tissue dielectric properties to identify and visualize abnormalities, with ultra-wideband (UWB) antennas configured in a two-port setup to improve signal penetration. The antenna, fabricated on an FR4 substrate with a dielectric constant (ε
