Multi-Strain Probiotic and Common Infections in Early Childhood Education Settings: A Randomised Controlled Trial.
Trial report in Journal of paediatrics and child health, 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
objectiveThis randomised controlled trial aimed to evaluate the effect of a multi-strain probiotic on the incidence of common infections among children in early childhood education (ECE) settings.
methodsProspective, randomised, double-blind, placebo-controlled trial was conducted using a multi-strain (mixture of 5 strains) probiotic at a daily dose of 10 billion active fluorescent units. Participating children were randomly assigned to either the intervention or control group. The supplementation period lasted 24 weeks, during which weekly questionnaires were administered to track the incidence of infections.
resultsA total of 118 children were enrolled in the trial. An intention-to-treat analysis revealed a 62% reduction in the incidence of gastrointestinal tract infections (GITIs) (incidence rate ratio: 1.62, p = 0.055) between the placebo and probiotic groups in the last 16 weeks of the study. Notably, it took up to 8 weeks for probiotics to exhibit a significant protective effect. However, probiotic supplementation had no impact on respiratory tract infections (RTIs). Additionally, probiotic use led to an estimated cost saving of AU$4748 in relation to reducing GITIs for 16 weeks after the protective effect was achieved.
conclusionMulti-strain probiotic has the potential to reduce the risk of GITIs among children in ECE settings, though no beneficial effect was observed on RTIs despite recording over 450 infections. Larger, multi-arm trials are recommended to further investigate this area.
