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

Deficiency in gammadelta T cells aggravates colitis in animal models suggesting that gammadelta T cells have regulatory properties. Therefore, proliferation, suppression and cytokine secretion of human gammadelta T cells were determined in vitro. Human peripheral gammadelta T cells were isolated from the whole blood of healthy donors by magnetic antibody cell sorting technology. The proliferation after CD3/CD28 stimulation was measured by (3)[H]thymidine incorporation. Interferon-gamma (IFN-gamma), interleukin-2 (IL-2), transforming growth factor-beta (TGF-beta) and IL-10 concentrations were measured by enzyme-linked immunosorbent assay; TGF-beta messenger RNA was also measured by reverse transcription-polymerase chain reaction. The expression of latency associated peptide (LAP), a TGF-beta complex component, intracellular cytokine content and T helper cell proliferation were measured by flow cytometry. Human gammadelta T cells showed poor proliferation upon CD3/CD28 stimulation and suppressed T helper cell growth stronger than CD4(+) CD25(+) T cells, although gammadelta T cells were FOXP3 negative. They secreted little IL-2 but high concentrations of IFN-gamma, IL-10 and TGF-beta. When looking at LAP expression the Vdelta1 subset was found to be the main TGF-beta producer compared to Vdelta2 T cells. Taken together, peripheral gammadelta T cells have in vitro a more potent regulatory potential than CD4(+) CD25(+) cells regarding T helper cell suppression. This is most likely the result of strong TGF-beta secretion, particularly by the Vdelta1 subset.
