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

In aesthetic sports, performance is closely linked to body composition; however, quantitative indicators for monitoring athlete conditions remain limited. Bioelectrical impedance analysis-derived phase angle (PhA) reflects cellular health; however, its relationship with performance-related variables in rhythmic gymnasts remains unclear. This study explored the relationships among PhA, body composition, bone density, training time, and jump performance in senior rhythmic gymnasts across competitive levels. Twenty-three female gymnasts (aged 15-22 years) were classified into a top group consisting of athletes who had won major domestic competitions in Japan (
