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

purposeTo determine the function of γδ T cells in early- and late-phase responses in allergic conjunctivitis.

methodsWild-type (WT) C57BL/6 and γδ T cell-deficient (TCR-δ(-/-)) mice were immunized intraperitoneally and challenged topically for 7 consecutive days with short ragweed pollen. Natural killer T (NKT) and γδ T cell-double-deficient mice were generated by treating TCR-δ(-/-) mice with anti-CD1d antibody. Allergic conjunctivitis was evaluated clinically, and the late-phase response was assessed by histopathology. Cytokine profiles were evaluated by ELISA. The afferent and efferent arms of allergic conjunctivitis were assessed by adoptive transfer of CD4(+) T cells from WT or TCR-δ(-/-) mice into naive TCR-δ(-/-) or WT mice.

resultsTCR-δ(-/-) mice had decreased clinical manifestations of allergic conjunctivitis compared with WT mice. TCR-δ(-/-) mice had decreased eosinophilic infiltration compared with WT mice. TCR-δ(-/-) mice produced less Th2-associated cytokines interleukin (IL)-4, -5, and -13 compared with WT mice. Clinical manifestations of allergic conjunctivitis were lowest in NKT cell-depleted TCR-δ(-/-) mice. However, late-phase allergic conjunctivitis in NKT cell-depleted, TCR-δ(-/-) mice was the same as TCR-δ(-/-) mice. Adoptive transfer of CD4(+) T cells revealed that γδ T cells are needed for the afferent and efferent arms of allergic conjunctivitis.

conclusionsγδ T cells are needed for full expression of both the clinical manifestations and the late phase of allergic conjunctivitis. Thus, γδ T cells have an important impact in the expression of allergic conjunctivitis and are a potential therapeutic target in the management of allergic diseases of the ocular surface.
