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

T cell receptor recombination is frequently described as a random or semi-random process that belies the now well-established principle that recombination is extremely biased towards the generation of particular receptor chains. Here we describe the experimental and theoretical work arising from new TCR repertoire sequencing approaches, including the recognition of high rates of public receptors across individuals, estimates of the size and distribution of receptors in the naive repertoire, and the roles of evolutionary, thymic, and peripheral selection in generating public, pathogen-specific responses. Molecular studies of recombination that have identified epigenetic, transcriptional, and topological contributions to variable segment usage are presented as examples of possible mechanisms shaped by natural selection to bias the TCR repertoire. Lastly, we suggest experimental approaches that might contribute to resolving some of the controversies in these areas.
