Effect of OM-85 BV on reducing bronchiectasis exacerbation in Chinese patients: the iPROBE study.
Article in Journal of thoracic disease, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 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
backgroundBronchiectasis is characterized by recurrent infectious exacerbations. No existing data inform preventive strategy for exacerbations beyond chronic macrolides. OM-85 BV, an immunostimulant, has been shown to prevent recurrent respiratory infections. We initiated this 1-year, multi-centered, double-blind, and controlled trial to investigate the PReventive effect of OM-85 BV on Bronchiectasis Exacerbations in Chinese patients (iPROBE).
methodsPatients with bronchiectasis aged 18 to 75 years, having at least one exacerbation in the past year, were randomized to receive, in addition to any respiratory medications, two courses of 7 mg of OM-85 BV or matching placebo (one capsule orally per day for 10 days a month) for 3 consecutive months, followed by 3 months without treatment. The primary outcomes included the number of acute infectious exacerbations and the time to first exacerbation. Secondary endpoints included patient-reported respiratory outcomes. Safety measures were also assessed.
resultsAmong the 196 participants, 99 were in the OM-85 BV group and 97 in the placebo group. At week 52, the mean number of acute exacerbations per patient was equal to 0.98 and 0.75, respectively, in the two groups (P=0.14). Difference in the time to first pulmonary exacerbation was not statistically significant (P=0.11). There was no statistically significant difference in any secondary end-points. The safety profile in the two arms was good and the majority of adverse events were mild.
conclusionsOM-85 BV did not demonstrate protection in decreasing pulmonary exacerbations of bronchiectasis in this trial performed in Chinese patients. It had good safety profile.
