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

purposeTo develop a noninvasive method for estimating dielectric properties over a wide frequency range from 50 to 600 MHz. Existing methods are limited in accuracy and provide single-frequency results. Furthermore, accurate knowledge of dielectric properties becomes more important, since medical device design and safety evaluation increasingly rely on computational modeling-based evaluation.

methodsTissue composition assessment was performed to find the most important factors for the dielectric properties, which were sodium, potassium, and water. These were measured with a 3D acquisition-weighted density-adapted stack-of-stars scheme (

resultsWith the Maxwell-Garnett mixture model, a 7.9% error in the real relative permittivity and a 4.0% error in the effective conductivity are found for the phantoms. The in vivo values are in a similar range to those reported in literature.

conclusionWe presented the feasibility of estimating dielectric properties over a wide frequency band with quantitative MRI, leading to a new method:
