Abstract

fetched live from OpenAlex

Introduction: Smoking increases inflammation and contributes to lung function decline with detrimental effects on asthma control. IRIDIUM study established clinical benefit of MF/IND/GLY vs FLU/SAL in patients with inadequately controlled asthma. We evaluated the effect of once-daily medium- (80/150/50µg) and high-dose MF/IND/GLY (160/150/50µg) vs twice-daily high-dose FLU/SAL (500/50µg) in ex- and never smokers. Methods: IRIDIUM (NCT02571777), a 52-wk, randomised, double-blind, double-dummy study included patients with symptomatic asthma (ACQ-7≥1.5), ≥1 exacerbation in previous year, FEV1 <80% and not current smokers. Trough FEV1 at wk 26 (primary end point) and exacerbations over 52 wks were evaluated by smoking history at screening. Results: ~80% patients were non-smokers; ~20% ex-smokers. Both doses of MF/IND/GLY showed greater improvements in trough FEV1 vs high-dose FLU/SAL, independent of smoking status (Figure 1A). There were trends for greater reduction in exacerbations with both doses of MF/IND/GLY vs high-dose FLU/SAL, with no clear difference dependent on smoking pattern (Figure 1B). Conclusion: Both doses of MF/IND/GLY showed benefit in lung function and asthma exacerbations vs high-dose FLU/SAL independent of smoking history, indicating no effect of smoking history on efficacy of MF/IND/GLY.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
