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

Dermatomyositis pathogenesis remains incompletely understood; however, recent work suggests a predominant IFN-1 response. We explored dermatomyositis pathogenesis by quantifying the inflammatory cells in the skin, comparing myeloid with plasmacytoid dendritic cell release of IFN-β, and assessing myeloid dendritic cell (mDC) contribution to hydroxychloroquine refractoriness. Immunohistochemistry was performed to assess cell-type expression in lesional skin biopsies from 12 patients with moderate-to-severe cutaneous dermatomyositis. Immunofluorescence, laser-capture microdissection, and flow cytometry were used to assess mDC release of IFN-β in lesional skin biopsies and blood of patients with dermatomyositis. Immunohistochemistry was utilized to determine whether myeloid or plasmacytoid dendritic cells were increased in hydroxychloroquine nonresponders. CD4+, CD11c+, and CD69+ cells were more populous in lesional skin of patients with dermatomyositis. mDCs colocalized with IFN-β by immunofluorescence and laser-capture microdissection revealed increased IFN-β mRNA expression by mDCs in lesional skin of patients with dermatomyositis. In blood, both mDCs and plasmacytoid dendritic cells were major producers of IFN-β in patients with dermatomyositis, whereas plasmacytoid dendritic cells predominately released IFN-β in healthy controls (P < 0.01). mDCs were significantly increased in the skin of hydroxychloroquine nonresponders compared with that in the skin of responders (P < 0.05). mDCs cells appear to play an important role in dermatomyositis pathogenesis and IFN-β production.
