Figure 2 Remission rate (A) and relapse rate (B) of probiotic group vs control group.

Figure 3 Inverted funnel plot analysis of the relative of remission rate. A: Inverted funnel plot analysis of the relative of remission rate between probiotics group and placebo group; B: Less than 12 mo group: Inverted funnel plot analysis of the relative of remission rate between probiotics group and non-probiotics group; C: Mild and middle UC group: Inverted funnel plot analysis of the relative of remission rate between probiotics group and non-probiotics group; D: Inverted funnel plot analysis of the relative of remission rate between probiotics group and placebo group; E: Inverted funnel plot analysis of the relative of remission rate between Bifidobacterium longum therapy group and non-probiotics therapy group.
