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

We performed a comprehensive analysis of T cell receptor (TCR) gamma rearrangements in T cell precursors of the mouse adult thymus. Using a sensitive quantitative PCR method, we show that TCRgamma rearrangements are present in CD44(+)CD25(+) Pro-T thymocytes much earlier than expected. TCRgamma rearrangements increase significantly from the Pro-T to the CD44(-)CD25(+) Pre-T cell transition, and follow different patterns depending on each Vgamma gene segment, suggesting that ordered waves of TCRgamma rearrangement exist in the adult mouse thymus as has been described in the fetal mouse thymus. Recombinations of TCRgamma genes occur concurrently with TCRdelta and D-Jbeta rearrangements, but before Vbeta gene assembly. Productive TCRgamma rearrangements do not increase significantly before the Pre-T cell stage and are depleted in CD4(+)CD8(+) double-positive cells from normal mice. In contrast, double-positive thymocytes from TCRdelta-/- mice display random proportions of TCRgamma rearranged alleles, supporting a role for functional TCRgamma/delta rearrangements in the gammadelta divergence process.
