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

It is commonly thought that disruption of the circadian clock increases the cancer incidence in humans and mice. However, it was found that disruption of the clock by the Cryptochrome (Cry) mutation in mice did not increase cancer rate in the mutant mice even after exposing the animals to ionizing radiation. Therefore, in this study we tested the effect of the Cry mutation on carcinogenesis in a mouse strain prone to cancer because of a p53 mutation, with the expectation that clock disruption in this sensitized background would further increase cancer risk. Paradoxically, we find that the Cry mutation protects p53 mutant mice from the early onset of cancer and extends their median lifespan approximately 50%, in part by sensitizing p53 mutant cells to apoptosis in response to genotoxic stress. These results suggest alternative therapeutic approaches in management of cancers associated with a p53 mutation.
