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

It is known that the level of interleukin-6 (IL-6) is higher in patients with active Behcet's disease (BD) than in those with inactive disease. Herpes simplex virus (HSV) type 1 inoculation of the earlobes of ICR mice resulted in the development of BD-like symptoms. To find out whether downregulation of IL-6 would affect the symptoms of BD, IL-6 small interfering RNA (siRNA) was administered to a BD mouse model. IL-6 siRNA was intraperitoneally injected into BD mice to downregulate IL-6 (n=9). IL-6 siRNA injection downregulated serum IL-6 level (118.9+/-114.4 pg ml(-1)) compared with scramble injection (439.4+/-378.0 pg ml(-1)) in BD mice (P=0.01). In seven out of nine IL-6 siRNA-injected BD mice, 77.8% improved and the severity score was decreased from 3.1+/-1.05 to 1.7+/-0.87 (P=0.005), whereas two out of six (33.3%) scramble-injected BD mice improved and the severity score changed from 2.5+/-0.84 to 2.0+/-1.41 (P=0.203). Foxp3, ROR gamma t, IL-17A, IL-17F and tumor necrosis factor-alpha were also influenced in IL-6 siRNA-injected BD mice compared with scramble-injected BD mice. Adoptive transfer of CD4+CD25+ cells to BD mice affected the decrease of IL-6 serum levels and were dependent on CD4+CD25+ cell numbers. These results showed that downregulation of IL-6 improved the inflammatory symptoms in BD mice through upregulation of regulatory T cells and inhibition of Th17 cells.
