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

backgroundA large fraction of the human genome is attributable to L1 retrotransposon sequences. Not only do L1s themselves make up a significant portion of the genome, but L1-encoded proteins are thought to be responsible for the transposition of other repetitive elements and processed pseudogenes. In addition, L1s can mobilize non-L1, 3'-flanking DNA in a process called 3' transduction. Using computational methods, we collected DNA sequences from the human genome for which we have high confidence of their mobilization through L1-mediated 3' transduction.

resultsThe precursors of L1s with transduced sequence can often be identified, allowing us to reconstruct L1 element families in which a single parent L1 element begot many progeny L1s. Of the L1s exhibiting a sequence structure consistent with 3' transduction (L1 with transduction-derived sequence, L1-TD), the vast majority were located in duplicated regions of the genome and thus did not necessarily represent unique insertion events. Of the remaining L1-TDs, some lack a clear polyadenylation signal, but the alignment between the parent-progeny sequences nevertheless ends in an A-rich tract of DNA.

conclusionsSequence data suggest that during the integration into the genome of RNA representing an L1-TD, reverse transcription may be primed internally at A-rich sequences that lie downstream of the L1 3' untranslated region. The occurrence of L1-mediated transduction in the human genome may be less frequent than previously thought, and an accurate estimate is confounded by the frequent occurrence of segmental genomic duplications.
