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

Exercise and diet are the best-known methods for attenuating aging-related health decline. However, exercise in older age has diminished gains of strength and agility, and a danger of unrepaired muscle damage. Improving the understanding of age-related differences in response to exercise, our results demonstrate that in old mice, downhill treadmill (eccentric) exercise causes increased influx of CD45+ cells (inflammation) and fibrotic index (fibrosis) in the heart and skeletal muscles. To explain these changes, we identified newly synthesized proteins through bio-orthogonal noncanonical amino acid tagging (BONCAT) and established that exercise exacerbated age-associated protein patterns through a dysregulated transforming growth factor (TGF)-β, Ras/MAPK/PI3Akt, and JAK/STAT pathways. Testing causality, we found that an inhibitor of TGF-β (Alk5 inhibitor, A5i) in combination with the age-diminished peptide oxytocin, previously shown to rejuvenate muscle and brain in sedentary animals, allowed aged mice to exercise without pathologies of skeletal and heart muscles and youthfully restored their de novo proteomes.
