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 evaluated the effect of a crude hot-water extract (HW) of quince (Cydonia oblonga Miller) fruit on immunoglobulin E (IgE)-dependent late-phase immune reactions of mast cells using in vitro system. Mast cell-like RBL-2H3 cells were treated with quince HW and late-phase reaction was then induced by stimulation with IgE + Antigen. Quince HW reduced the elevation of interleukin-13 and tumor necrosis factor-α expression level. Furthermore, quince HW suppressed these cytokine expressions of mouse bone marrow-derived mast cells (BMMCs), a normal mast cell model. Leukotriene C(4) and prostaglandin D(2) production in BMMCs after 1 and 6 h of stimulation, respectively, were also reduced by treating the cells with quince HW. We found that the induction of intracellular cyclooxygenase (COX)-2 expression but not COX-1 expression in BMMCs was reduced by quince HW. These results suggest that quince HW has an inhibitory effect on broad range of the late-phase immune reactions of mast cells.
