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

Muscle stem cells, or satellite cells (SCs), decline in number throughout the lifespan and may become senescent in very old age. Whether and how remaining SCs contribute to muscle adaptation in the oldest-old is unclear. Using acute mechanical overload in geriatric SC replete and depleted mice (28-month-old) combined with single-cell RNA-sequencing, we show: (i) subsets of geriatric SCs display signs of senescence as well as normal fate progression during overload, (ii) SCs express markers that may contribute to the regulation of innervation, (iii) the presence of SCs during overload enhances global intercellular communication and increases mRNA levels of the cell surface receptor
