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

The term "muscle quality" is widely used in both research and clinical settings, yet a universally accepted definition currently does not exist. Studies addressing "muscle quality" encompass a broad range of functional and morphological characteristics of skeletal muscle, leading to inconsistent interpretations. Aligning with global efforts to adopt standardized and precise terminology, this paper aims to clarify the most frequently assessed parameters under the umbrella of "muscle quality", describe the accurate definitions, and emphasize their clinical significance. Establishing a future unified framework and terminology will be essential for advancing research, ensuring comparability across studies, and reinforcing the clinical applicability of muscle health assessments. Until then, muscle composition, muscle architecture, and muscle-specific strength may serve as appropriate terms to describe the morphological and functional aspects, respectively.
