Limosilactobacillus reuteri DSM 17938 and PTA 6475 as adjunct in Helicobacter pylori therapy: Systematic review and meta-analysis

Figure 2 Risk of bias assessment for the randomized controlled trials included in the meta-analysis. A: Summary of review authors’ judgments across seven domains of the Cochrane Risk of Bias tool for each included study. Green circles indicate low risk of bias, yellow circles indicate unclear risk, and red circles indicate high risk; B: Proportion of studies rated as low, unclear, or high risk of bias for each domain. Most studies showed a low risk of bias in domains related to outcome data and selective reporting. Higher or unclear risk was observed primarily in domains related to blinding and allocation concealment.
