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

Severe muscle fat infiltration is a contributing factor to muscle loss, particularly in the spinal sarcopenia population. However, the underlying mechanism largely remains elusive. Here, we identified the intramuscular fat fraction (IMFF), rather than perimuscular fat fraction, as an independent determinant of trunk muscle strength. Individuals with higher IMFF (10-15% and >15%) exhibited significantly lower paraspinal muscle mass and strength compared to those with lower IMFF (<5%). Using single-nucleus RNA sequencing, we established the first cellular atlas of fat-infiltrated paraspinal muscle, revealing profound remodeling of muscle architecture, extracellular matrix organization, and satellite cell niches. Among the adipose-derived factors, ANGPTL4 emerged as a key paracrine suppressor of myogenesis, acting through upregulation of syndecan-2 (SDC2) in satellite cells. Inhibition of SDC2 partially rescued ANGPTL4-induced myogenic impairment in C2C12 cells. Furthermore, we identified a GPC3
