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

At the Tcrb locus, Vβ-to-Jβ rearrangement is permitted by the 12/23 rule but is not observed in vivo, a restriction termed the “beyond 12/23” rule (B12/23 rule). Previous work showed that Vβ recombination signal sequences (RSSs) do not recombine with Jβ RSSs because Jβ RSSs are crippled for either nicking or synapsis. This result raised the following question: how can crippled Jβ RSSs recombine with Dβ RSSs? We report here that the nicking of some Jβ RSSs can be substantially stimulated by synapsis with a 3′Dβ1 partner RSS. This result helps to reconcile disagreement in the field regarding the impact of synapsis on nicking. Furthermore, our data allow for the classification of Tcrb RSSs into two major categories: those that nick quickly and those that nick slowly in the absence of a partner. Slow-nicking RSSs can be stimulated to nick more efficiently upon synapsis with an appropriate B12/23 partner, and our data unexpectedly suggest that fast-nicking RSSs can be inhibited for nicking upon synapsis with an inappropriate partner. These observations indicate that the RAG proteins exert fine control over every step of V(D)J cleavage and support the hypothesis that initial RAG binding can occur on RSSs with either 12- or 23-bp spacers (12- or 23-RSSs, respectively).
