1 Efficacy level A (among the most effective): probiotics that are significantly superior to placebo and at least 1 probiotic in level B. Efficacy level B: probiotics that are more effective than placebo, but not superior to any other of the probiotic(s) superior to placebo. Efficacy level C (among the least effective): probiotics with no significant difference compared to placebo. 2 The network meta-analysis results were the efficacy of probiotics compared to placebo. Mean difference with 95% confidence intervals in parentheses. Abbreviations: GRADE, The Grading of Recommendations, Assessment, Development and Evaluation system; H, high; M, moderate; L, low.
