Systematic review and meta-analysis of Saccharomyces boulardii in adult patients

Figure 3 Forest plot of meta-analysis of ten randomized controlled trials measuring protective effect after treatment with S. boulardii or placebo for the prevention of antibiotic-associated diarrhea in adult patients. The x-axis depicts effect size, with black dot denoting the relative risk and the line indicating 95% CI, with the size of the grey box proportional to the study size. Relative risks to the left of RR = 1 denote study favored the probiotic, RR to the right denotes the study favors the placebo. Overall, pooled RR was 0.47 (0.35-0.63).
