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

Genes encoding immunoglobulin heavy chains (Igh) are assembled by rearrangement of variable (V(H)), diversity (D(H)) and joining (J(H)) gene segments. Three critical constraints govern V(H) recombination. These include timing (V(H) recombination follows D(H) recombination), precision (V(H) gene segments recombine only to DJ(H) junctions) and allele specificity (V(H) recombination is restricted to DJ(H)-recombined alleles). Here we provide a model for these universal features of V(H) recombination. Analyses of DJ(H)-recombined alleles showed that DJ(H) junctions were selectively epigenetically marked, became nuclease sensitive and bound RAG recombinase proteins, which thereby permitted D(H)-associated recombination signal sequences to initiate the second step of Igh gene assembly. We propose that V(H) recombination is precise, because these changes did not extend to germline D(H) segments located 5' of the DJ(H) junction.
