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

BACKGROUND AND

objectivesThe role of serum copper in modulating body composition in patients with spinal muscular atrophy (SMA) remains uncertain. This study aimed to illustrate the correlation between serum copper concentration and body composition in children with SMA. METHODS AND STUDY

designThis study was conducted at a pediatric medical center in China from July 2019 to August 2022. The study included anthropometric measurements, serum analysis for copper, magnesium, zinc, and iron, as well as comprehensive body composition assessments. Multivariate analysis was utilized to assess the connection between serum copper concentration and body composition metrics.

resultsThis cross-sectional analysis included 87 patients [median (IQR) age: 7 years (5-10), 57.5% male] diagnosed with SMA receiving comprehensive multi-disciplinary management. The results revealed a positive association between serum copper concentration and both fat mass percentage (β = 0.50, 95% confidence interval (CI): 0.07 to 0.92, p = 0.025) and fat-muscle ratio (β = 0.02, 95% CI: 0.01 to 0.03, p = 0.009). Conversely, a negative correlation was found between serum copper concentration and muscle mass percentage (β = -0.70, 95% CI: -1.11 to -0.29, p = 0.001).

conclusionsThese findings suggest a correlation between copper concentration and body composition in SMA, offering valuable insights for addressing metabolic dysregulation in these patients.
