Oral Bacterial Lysate OM-85 Prevents Respiratory Tract Infections in Asthma: The OMRIA RWE Study.
Article in Journal of asthma and allergy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled it.
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
Background: OM-85 is a well-characterized bacterial lysate with antiviral properties, enhancement of airway epithelial barrier function, and tolerance induction. However, real-world evidence is needed to evaluate its effectiveness as an add-on therapy in patients with allergic asthma. Methods: This retrospective cohort study analyzed medical records of 137 adults with moderate to severe allergic asthma over 12 months. Patients receiving standard of care (SoC) asthma therapy alone (GINA step 4, n = 67) were compared to those on SoC+OM-85 (n = 70). All symptom episodes (CEPs) indicative of respiratory tract infections (RTIs) were recorded, and a 3-scale mean severity index (mSI) was calculated. Propensity score weighting was used for Poisson and linear regression analyses. Results: Patients on OM-85 demonstrated significant reductions in the number of CEPs (60%), asthma exacerbations (71%), unscheduled visits (72%), oral corticosteroid courses (73%), and antibiotic cycles (67%). The mSI was 1.15 points lower in the OM-85 group (p < 0.001). Conclusion: OM-85 as an add-on to standard asthma therapy significantly reduced RTI-related episodes, exacerbations, and healthcare utilization while lowering symptom severity in adults with allergic asthma.
