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

The lymphoid-specific proteins RAG1 and RAG2 initiate V(D)J recombination by introducing DNA double-strand breaks at the recombination signal sequences (RSSs). In addition to DNA cleavage, the versatile RAG1/2 complex is capable of catalyzing several other reactions, including hybrid joint formation and the transposition of signal ends into a second DNA. Here we show that the RAG1/2 complex also mediates an unusual strand transfer reaction, inverse transposition, in which non-RSS DNA is cleaved and subsequently transferred to an RSS sequence by direct transesterification. Characterization of the reaction products and requirements suggests that inverse transposition is related to both hybrid joint formation and signal-end transposition. This aberrant activity provides another possible mechanism for some chromosomal translocations present in lymphoid tumors.
