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

Osteoporosis (OP) is a common skeletal disease involving low bone mineral density (BMD) that often leads to fragility fracture, and its development is affected by multiple cellular pathologies and associated with marked epigenetic alterations of osteogenic genes. Proper physical exercise is beneficial for bone health and OP and reportedly possesses epigenetic modulating capacities; however, whether the protective effects of exercise on OP involve epigenetic mechanisms is unclear. Here, we report that epigenetic derepression of nuclear factor erythroid derived 2-related factor-2 (Nrf2), a master regulator of oxidative stress critically involved in the pathogenesis of OP, mediates the significant osteoprotective effects of running exercise (RE) in a mouse model of OP induced by ovariectomy. We showed that Nrf2 gene knockout (Nfe2l2
