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

Previous studies have suggested that gamma-delta T cells play an important role in the pathogenesis of ankylosing spondylitis (AS). In this pilot study, the peripheral blood mononuclear cells (PBMCs) of patients with ankylosing spondylitis (AS) and healthy volunteers were stained and analyzed by flow cytometry to distinguish gamma-delta T cells and its subtypes, and then to report the distribution of gamma-delta T cells and iyts subtypes and their correlation with ankylosing spondylitis. A total of 17 patients with active AS and 10 age- and gender- matched healthy volunteers were enrolled in this study, and their peripheral blood were drawn to collect mononuclear cells (PBMCs). Flow cytometry was used to analyze gamma-delta T cell subpopulations by measuring the surface and intracellular expressions of phenotypic markers. Serum levels of inflammatory and bone turnover markers were measured, and their correlations with subpopulations of gamma-delta T cells were evaluated. In patients with AS, the Vdelta2 fractions within gamma-delta T cells and CD3+ T cells decreased significantly, in particular, the proportions of CD27+ Vdelta2 T cells, CD86+CD80+ Vdelta1 T cells, and IL17A-secreting and TNFalpha-secreting Vdelta1 T cells within the parental cells decreased significantly. gamma-delta T cells/PBMCs, Vdelta2 cells/gamma-delta T cells, and Vdelta2 cells/CD3+ T cells were negatively correlated with CRP, whereas Vdelta1 cells/CD3+ T cells were negatively correlated with ESR. Vdelta1 cells/gamma-delta T cells were positively correlated with CRP, gamma-deltaT cells/PBMCs were positively correlated with beta-CTx, CD69+CD25+ and IL-17A-secreting Vdelta1 cells were positively correlated with TP1NP, and CD69+CD25+ Vdelta1 and Vdelta2 cells were positively correlated with osteocalcin. Decreases in peripheral Vdelta2, CD27+ Vdelta2, CD86+CD80+ Vdelta1, and IL17A or TNFalpha-secreting Vdelta1 T cells are associated with AS. The correlations between gamma-delta T cell subpopulations and CRP and the CD69+CD25+ subpopulation with TP1NP or osteocalcin suggest that an imbalance in peripheral gamma-delta T cell subpopulations contributes to the pathogenesis of AS.
