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

objectiveLocalized bioimpedance spectroscopy (BIS) is a non-invasive technique for assessing muscle tissue properties. This study examined the test-retest reliability of BIS measurements on the upper trapezius muscle and the effects of body positioning and electrode reapplication. APPROACH: Ten healthy adults (ages 18-30) with no history of neck or shoulder pain participated in the study. BIS measurements were collected over two days across three body positions (prone, seated, seated with neck bent) and with different electrode applications. Key impedance parameters were extracted from Cole-Cole plots. We evaluated measurement reliability, variability, and the minimum detectable change. MAIN

resultsBIS measures demonstrated high reliability for primary impedance parameters when body positioning was controlled, whereas model-derived parameters showed greater variability. Impedance parameters differed if the participants were seated or lying prone but were not sensitive to bending the neck to the side. Electrode reapplication did not significantly alter measures unless applied a third time, and sex-related differences were not significant. SIGNIFICANCE: BIS appears to be a reliable method for assessing upper trapezius muscle tissue properties when body position is standardized. Future research should explore BIS applications in larger and more diverse populations and evaluate its potential clinical utility.
