Digest: A single genetic origin and a role for bone development pathways in repeated losses of flight in steamer ducks.
Article in Evolution; international journal of organic evolution, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Is there evidence for convergence in the molecular mechanisms underlying the loss of flight in the avian evolutionary tree? Campagna et al. used genomic data to investigate the genetic basis of flightlessness in steamer ducks, a recently diverged clade that is polymorphic with respect to flight. They found an association between morphological changes related to flightlessness and several genes, one of which is involved in growth and bone development, providing evidence for a single genetic origin for flightlessness.
