A Summary of a Cochrane Review: Probiotics to Prevent Acute Upper Respiratory Tract Infections
Bibliographic record
Abstract
Review authors in the Cochrane Collaboration conducted a systematic review to evaluate the effects of probiotics to prevent acute upper respiratory tract infections (URTIs) such as the common cold and acute sinusitis in people at average risk of a URTI. After extensive searching for all relevant studies, the authors identified 12 randomized controlled trials that tested the effects of different types of probiotics on the development or duration of a URTI episode. Six studies were in children, 3 in adults, and 2 in older people. This summary presents the findings from this review. Probiotics are live microorganisms, primarily bacteria, that are believed to provide health benefits when ingested. There are several different types and strains of probiotics that are commonly used, such as Lactobacillus, Streptococcus, and Bifidobacterium. Probiotics can be taken with milk products, as a powder, or in capsules and do not require a prescription. There has been some research into whether taking probiotics could p...

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
