Abstract

fetched live from OpenAlex

Asthma is a heterogeneous disorder, and the prevalence is increasing worldwide. The BCG vaccine is hypothesized to lower the risk of asthma by modulating specific aspects of T-cell mediated immunity (termed Th1 and Th2). We conducted a case-control study to determine the relationship between BCG vaccine given to children born and raised in Quebec and asthma in adult subjects. 93 case subjects with a clinical diagnosis of asthma and 118 control subjects without asthma answered a standardized questionnaire, and BCG vaccination status was verified in a central registry. After adjusting for potential confounders, vaccination with BCG after the age of one was associated with a reduced odds of adult-onset asthma (odds ratio: 0.3 (0.1-0.98)), and specifically of adult-onset atopic asthma (odds ratio: 0.2 (0.1-0.9)). These results suggest a critical time frame in immune system maturation during which administration of BCG vaccine may lower the risk of adult-onset asthma.

Not 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.
