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

Multi-glycoside of Tripterygium wilfordii Hook. f.(GTW) possesses anti-inflammatory and immunosuppressive properties, and has been used as a traditional treatment for psoriasis for many years, although the underlying immunological mechanisms remain poorly understood. The T helper (Th)17 cell response is considered to play a major role in the pathogenesis of psoriasis. Th17 cells are implicated in the mechanism of pathogenesis of imiquimod (IMQ)‑induced skin inflammation. Using a mouse model, we demonstrated that GTW protected mice from developing psoriasis-like lesions induced by topical IMQ administration. This protection was associated with significantly decreased mRNA levels of Th17 cytokines such as interleukin (IL)-17A, IL-17F and IL-22 in mouse skin samples as well as fewer IL-17-secreting splenic CD4+ lymphocytes in IMQ-exposed mice. There were no significant effects on the proportion of CD4+ interferon (IFN)-γ+ T cells, CD4+IL-4+ T cells and CD4+CD25+Foxp3+ Treg cells in the spleen cells. Taken together with the unchanged mRNA levels of Th1 cytokine IFN-γ, Th2 cytokine IL-4 and Treg cytokine IL-10 in IMQ-exposed mouse skin following GTW administration, our findings suggest that the immunosuppressive effect of GTW in psoriasis is exerted mainly on Th17 cells, rather than on Th1, Th2 or Treg cells. Furthermore, we showed that GTW suppressed Th17 function through the inhibition of STAT3 phosphorylation. These results have the potential to pave the way for the use of GTW as an agent for the treatment of psoriasis.
