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

Mitohormesis, whereby transient mitochondrial stress induces adaptive signaling, promotes organismal resilience and longevity in invertebrates, but how this operates in mammals and the underlying metabolic signals involved remain unclear. Using a mouse model of mitohormesis, we show that transient mitochondrial superoxide stress during embryogenesis reprograms the adult heart to enhance mitochondrial biogenesis and antioxidant capacity. These adaptations confer protection against mitochondrial and oxidative injury in models of doxorubicin-induced cardiotoxicity, preserving mitochondrial content and preventing cardiac dysfunction and remodeling. Using a cell model of superoxide-mediated mitohormesis, we find that inhibition of mitochondrial aconitase promotes citrate export to the cytosol, where its conversion to acetyl-coenzyme A drives histone acetylation and mitohormetic protection from oxidative stress. Preventing mitochondrial citrate export abolishes these adaptations, while
