Causes and consequences of divorce in a long-lived socially monogamous bird.
Article in Ecology letters, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
In socially monogamous species, sexual selection not only depends on initial mate choice but also mate switching. To date, studies lack assessment of (1) differences between passive (widowhood) and active (divorce) mate switching, (2) longer term fitness consequences (beyond the season post-divorce) and (3) how age masks reproductive costs and benefits of divorce. We investigated causes and short- and long-term consequences of mate switching and their age dependence using longitudinal data on Seychelles warblers (Acrocephalus sechellensis). Young and old males, but not females, divorced most frequently. Divorce propensity declined with pair-bond duration and reproductive success in both sexes, but mate switching did not incur short-term costs. Divorcees did not gain short- or long-term fitness benefits compared to non-divorcees. Rather, female early-life divorcees that lost their breeding position had lower survival than females that never divorced. Divorce is likely a strategy to escape poor-quality partnerships, but not all divorcees benefit from divorcing.
