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

A major subset of human peripheral blood γδ T cells expresses the Vγ2Vδ2 T cell receptor and responds to malignant or infectious diseases. We noted significant differences in the numbers of Vγ2Vδ2 T cells in blood samples from healthy Caucasian CA or African American (AA) donors. On average, CA donors had 3.71% ± 4.37% Vδ2 cells (as a percentage of total lymphocytes) compared with 1.18% ± 2.14% Vδ2 cells for AA donors (p < 0.0001). Age and race had the greatest impact on Vδ2 cell levels; the effect of age was similar for both racial groups. The Vδ2 cell population was dominated, for both donor groups, by cells expressing the Vγ2-Jγ1.2 Vδ2 T cell receptor, an apparent result of strong positive selection and there was substantial overlap in the public Vγ2 clonotypes from both racial groups. Mechanisms for selection and amplification of Vδ2 cells are nearly identical for both groups, despite the significant difference in baseline levels. These data show that appropriate controls, matched for age and race, may be required for clinical studies of Vγ2Vδ2 T cells in infectious disease or cancer and raise important questions about the mechanisms regulating the levels of circulating Vδ2 cells.
