A Long-term Study of the Antiinflammatory Effect of Low-dose Budesonide Plus Formoterol versus High-dose Budesonide in Asthma
Bibliographic record
Abstract
Adding inhaled long-acting beta(2)-agonists to a low dose of inhaled corticosteroids (ICS), results in better clinical asthma control than increasing the dose of ICS. However, this approach may mask underlying airway inflammation. In a double-blind parallel-group study, we evaluated the effect of adding formoterol to a low dose of budesonide, compared with a higher dose of budesonide, on the composition of induced sputum. After a 4-wk run-in period of treatment with budesonide (800 microg, twice daily), 60 patients with moderate asthma were randomly assigned to a 1-yr treatment with 400 microg of budesonide plus placebo, twice daily (BUD800), or 100 microg of budesonide plus 12 microg of formoterol, twice daily (BUD200+F). All drugs were administered via Turbuhaler. Budesonide (800 microg, twice daily) during run-in significantly reduced median sputum eosinophils from 4.5 to 0.68%. No significant changes in the proportion of eosinophils, EG2(+) cells, other inflammatory cells, or ECP levels in sputum were observed over the ensuing 1-yr treatment with BUD200+F or BUD800. Clinical asthma control was not significantly different between both groups. In conclusion, no significant differences in sputum markers of airway inflammation were observed during a 1-yr treatment with a low dose of inhaled budesonide plus formoterol compared with a higher dose of budesonide.

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.
