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

Humans form 2 groups based on their innate immunity to Epstein-Barr virus (EBV). Group 1 makes a strong natural killer (NK)-cell and γδ T-cell response, whereas group 2 makes a strong NK-cell response, but a weak γδ T-cell response. To investigate the underlying basis for this difference in γδ T-cell immunity to EBV, we used next-generation sequencing to compare the γδ T-cell receptor (TCR) repertoires of groups 1 and 2. In the absence of EBV, group 1 TCRγ chains are enriched for complementarity determining region 3 (CDR3s) containing JγP, whereas group 2 TCRγ chains are enriched for CDR3s containing Jγ2. In group 1 donors, EBV activates many γδ T cells expressing Vγ9JγP, inducing proliferation that produces a large population of activated effector cells. The TCRs using Vγ9JγP are closely related to the TCRs of γδ T cells that respond to phosphoantigens. In group 2 donors, EBV activates a small subpopulation of γδ T cells, most expressing Vγ9JγP. In conclusion, we find that differences in the TCRγ-chain repertoire underlie the differential response of group 1 and group 2 to EBV.
