Forest graph and ranking probability graph on outcome ①. A: Methylprednisolone, B: placebo, C: prednisolone, D: IFNb-1α, E: brain-derived neurotrophic factor, F: CSF filtration, G: PE, I: IVIg 0.4–0.5 g/kg daily for 4–5 days, J: PE followed by IVIg, K: immunoadsorption followed by IVIg, L: immunoadsorption, M: IVIg 1 g/kg daily for 2 days, N: IVIg 0.4 g/kg/d for 3 days, O: Half-times of PE. (A–C): Forest plots (references were placebo, PE, and IVIg, respectively), indicate relative effect results compared with placebo group, PE, and IVIg. (D): Ranking probability graph of outcome ①. The heights of bars represent the probability to be a certain rank; for every therapy, bars from left to right represent ranks from worst to best.
