Intron presence-absence polymorphisms in Daphnia.
Article in Molecular biology and evolution, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 19 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
Here, we report 2 novel intron gains segregating in populations of Daphnia pulex endemic to Oregon. These novel introns do not have an obvious source and are not present in any D. pulex populations outside Oregon, other species of Daphnia that we examined, or any other organism for which sequence data are available. Furthermore, the novel introns are both found in the same gene, a Rab GTPase (rab4), and they appear to differ in their insertion site by one base pair, providing some support to the proto-splice site hypothesis. The rarity of intron-gain polymorphisms is questioned as we discovered 2 events in an initial survey of only 6 nuclear loci in 36 Daphnia individuals. Neutrality tests failed to ascertain a clear selective effect for either intron insertion, and a significant difference in recombination rate was not observed in alleles that contain the novel intron insertion versus alleles lacking it. We conclude that one novel intron insertion segregating at high frequencies in Daphnia populations in Oregon is unlikely to be adaptive and may result from the reduced efficacy of selection in isolated populations of small effective size.
