Probiotics in 14-day triple therapy for Asian pediatric patients with Helicobacter pylori infection: a network meta-analysis. 

In a clinical study designed to assess the effect of Probiotic-3 supplementation on H. pylori clearance, 182 patients were randomized to standard of care supplemented with daily Probiotic-3, or to standard of care alone, for 14 days. The clearance rate with Probiotic-3 supplementation was 84%, as compared to 63% for standard therapy.
