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

Gene conversion is a type of homologous recombination that leads to transfer of genetic information among homologous DNA sequences. It can be categorized into two classes: homogenizing and diversifying gene conversions. The former class results in neutralization and homogenization of any sequence variation among repetitive DNA sequences, and thus is important for concerted evolution. On the other hand, the latter functions to increase genetic diversity at the recombination-recipient loci. Thus, these two types of gene conversion play opposite roles in genome dynamics. Diversifying gene conversion is observed in the immunoglobulin (Ig) loci of chicken, rabbit, and other animals, and directs the diversification of Ig variable segments and acquisition of functional Ig repertoires. This type of gene conversion is initiated by the biased occurrence of recombination initiation events (e.g., DNA single- or double-strand breaks) on the recipient DNA site followed by unidirectional homologous recombination from multiple template sequences. Transcription and DNA accessibility is also important in the regulation of biased recombination initiation. In this review, we will discuss the biological significance and possible mechanisms of diversifying gene conversion in somatic cells of eukaryotes.
