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

Lifetime reproductive success (LRS) is what counts in terms of evolution, but investments in reproduction entail costs for an organism. The idea that telomere dynamics may be shaped in response to such costs is already established; however, we still lack information on whether this relation translates to overall fitness. Here, we quantified LRS (number of fledged young) and longitudinal telomere dynamics of small passerine birds-the blue tits ( Cyanistes caeruleus). We found that individual telomere erosion rate was positively associated with lifetime fledgling number. Birds with more fledged young experienced increased telomere attrition. We show that telomere attrition rate, but not telomere length, is related to individual fitness and suggest that telomere dynamics may underlie reproductive costs experienced by animals as a consequence of prioritizing their lifetime fitness. This is the first study, to our knowledge, to provide evidence that more pronounced telomere erosion is associated with higher fitness gain.
