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

RAG1/2 (RAG) is an RNH-type DNA recombinase specially evolved to initiate V(D)J gene rearrangement for generating the adaptive immune response in jawed vertebrates. After decades of frustration with little mechanistic understanding of RAG, the crystal structure of mouse RAG recombinase opened the flood gates in early 2015. Structures of three different chordate RAG recombinases, including protoRAG, and the evolutionarily preceding transib transposase have been determined in complex with various DNA substrates. Biochemical studies along with the abundant structural data have shed light on how RAG has evolved from an ordinary transposase to a specialized recombinase in initiating gene rearrangement. RAG has also become one of the best characterized RNH-type recombinases, illustrating how a single active site can cleave the two antiparallel DNA strands of a double helix.
