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

IL-33 and its soluble receptor and cell-associated receptor (ST2L) are all increased in clinical and experimental asthma. The present study addressed the hypothesis that ST2L impairs the therapeutic effects of CpG in a fungal model of asthma. C57BL/6 mice were sensitized to Aspergillus fumigatus and challenged via i.t. instillation with live A. fumigatus conidia. Mice were treated with IgG alone, anti-ST2L monoclonal antibody (mAb) alone, CpG alone, IgG plus CpG, or anti-ST2L mAb plus CpG every other day from day 14 to day 28 and investigated on day 28 after conidia. Lung ST2L and toll-like receptor 9 protein expression levels concomitantly increased in a time-dependent manner during fungal asthma. Therapeutic blockade of ST2L with an mAb attenuated key pathological features of this model. At subtherapeutic doses, neither anti-ST2L mAb nor CpG alone affected fungal asthma severity. However, airway hyperresponsiveness, mucus cell metaplasia, peribronchial fibrosis, and fungus retention were markedly reduced in asthmatic mice treated with the combination of both. Whole lung CXCL9 levels were significantly elevated in the combination group but not in the controls. Furthermore, in asthmatic mice treated with the combination therapy, dendritic cells generated significantly greater IL-12p70 with CpG in vitro compared with control dendritic cells. The combination of anti-ST2L mAb with CpG significantly attenuated experimental asthma, suggesting that targeting ST2L might enhance the therapeutic efficacy of CpG during allergic inflammation.
