Effectiveness of Lactobacillus-supplemented eradication therapy for Helicobacter pylori: a systematic review and meta-analysis of randomized controlled trials.
Synthesis in European journal of clinical pharmacology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeHelicobacter pylori eradication therapies supplemented with Lactobacillus spp. may improve eradication rates and reduce adverse events by modulating gut microbiota and immune responses. This meta-analysis aimed to evaluate the efficacy and safety of Lactobacillus-supplemented Helicobacter pylori eradication therapy.
methodsWe systematically searched for randomized controlled trials (RCTs) comparing standard Helicobacter pylori eradication therapy with and without Lactobacillus in PubMed, Embase, and Cochrane Library up to August 2026. The primary outcome was eradication success, and the secondary outcome was adverse events. We calculated pooled risk ratios (RR) with 95% confidence intervals (CIs) using a random-effects model. We also estimated the number needed to treat (NNT) for eradication success and conducted subgroup analyses by antibiotic therapy type, duration of antibiotic treatment, Lactobacillus strain type, Lactobacillus dosage, period of Lactobacillus use, probiotic formulation, geographical region, and age range. This review was registered in PROSPERO (CRD42024611138).
resultsThirty-two RCTs (4,010 patients) were included. Lactobacillus-supplemented eradication therapy improved eradication success (RR 1.10; 95%CI 1.05-1.14; NNT 13) and reduced the risk of adverse events (RR 0.70; 95%CI 0.58-0.84). Subgroup analyses showed significant differences in eradication success by antibiotic regimen and in adverse event risk by age group. Improved eradication success with Lactobacillus-supplemented eradication therapy was observed only with triple therapy regimens, whereas adverse event risk was reduced only among adults.
conclusionLactobacillus-supplemented eradication therapy was associated with a 10% relative increase in Helicobacter pylori eradication success and a 30% relative reduction in treatment-related adverse events compared with the control group.
