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

Chicken repeat 1 (CR1) retroposons are the most abundant superfamily of transposable elements in the genomes of birds, crocodilians, and turtles. However, CR1 mobilization remains poorly understood. In this article, I document that the diverse CR1 lineages of land vertebrates share a highly conserved hairpin structure and an octamer microsatellite motif at their very 3' ends. Together with the presence of these same motifs in the tails of CR1-mobilized short interspersed elements, this suggests that the minimum requirement for CR1 transcript recognition and retrotransposition is a complex >50-nt structure. Such a highly specific recognition sequence readily explains why CR1-dominated genomes generally contain very few retrogenes. Conversely, the mammalian richness in retrogenes results from CR1 extinction in their early evolution and subsequent establishment of L1 dominance.
