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

To obtain structural information on the early stages of V(D)J recombination, we isolated a complex of the core RAG1 and RAG2 proteins with DNA containing a pair of cleaved recombination signal sequences (RSS). Stoichiometric and molecular mass analysis established that this signal-end complex (SEC) contains two protomers each of RAG1 and RAG2. Visualization of the SEC by negative-staining electron microscopy revealed an anchor-shaped particle with approximate two-fold symmetry. Consistent with a parallel arrangement of DNA and protein subunits, the N termini of RAG1 and RAG2 are positioned at opposing ends of the complex, and the DNA chains beyond the RSS nonamer emerge from the same face of the complex, near the RAG1 N termini. These first images of the V(D)J recombinase in its postcleavage state provide a framework for modeling RAG domains and their interactions with DNA.
