Tracking a recent horizontal transfer event: The P-element reaches Brazilian populations of Drosophila simulans.

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
The "cut-and-paste" P-element present in some Diptera illustrates two important transposable elements abilities: to move within genomes and to be transmitted between non-mating species, a phenomenon known as horizontal transposon transfer (HTT). Recent studies reported a HTT of the P-element from Drosophila melanogaster to D. simulans. P-elements first appeared in D. simulans European samples collected in 2006 and spread across several populations from Europe, Africa, North America and Japan within seven years. Nevertheless, no P-element was found in South American populations of D. simulans collected between 2002 and 2009. We investigated the presence of the P-element in D. simulans collected in five Brazilian localities between 2018 and 2019, using a combination of methodologies such as PCR, DNA sequencing and FISH on chromosomes. Our experiments revealed the presence of the P-element in all sampled individuals from the five localities. The number of P-elements per individual varied from 11 to 20 copies and truncated copies were also observed. Altogether, our results showed that P-element invasion in D. simulans is at an advanced stage in Brazil and, together with other recent studies, confirms the remarkable rapid invasion of P-elements across worldwide D. simulans populations.
