Abstract

fetched live from OpenAlex

RATIONALE: Budesonide/formoterol and tiotropium are commonly used maintenance treatments for patients with chronic obstructive pulmonary disease. Combining these medications may provide additional benefits. OBJECTIVES: To assess the efficacy and tolerability of budesonide/formoterol added to tiotropium in patients eligible for inhaled corticosteroid/long-acting beta(2)-agonist combination therapy. METHODS: In this 12-week, randomized, double-blind, parallel-group, multicenter study, after a 2-week run-in, 660 subjects (75% male; mean age, 62 yr; FEV(1), 1.1 L; 38% predicted normal), 40 years of age or older, received tiotropium (18 microg once daily) plus either budesonide/formoterol (320/9 microg) (n = 329) or placebo (n = 331) twice daily. MEASUREMENTS AND MAIN RESULTS: Clinic predose (primary outcome) and postdose FEV(1), predose and postdose forced vital capacity and inspiratory capacity, and health status were measured. Other outcomes included daily measurements taken at home (pre- and postdose morning FEV(1) and peak expiratory flow, morning symptoms and activities, and morning reliever use), severe exacerbations, and tolerability. Over the treatment period, budesonide/formoterol plus tiotropium significantly increased predose FEV(1) by 6% (65 ml) and postdose by 11% (123 and 131 ml at 5 and 60 min postdose, respectively) versus tiotropium alone (both P < 0.001). Other outcomes all significantly improved with budesonide/formoterol plus tiotropium versus tiotropium alone. The number of severe exacerbations decreased by 62% (rate ratio, 0.38; 95% confidence interval, 0.25-0.57; P < 0.001). Both treatments were well tolerated. CONCLUSIONS: In patients with chronic obstructive pulmonary disease, budesonide/formoterol added to tiotropium versus tiotropium alone provides rapid and sustained improvements in lung function, health status, morning symptoms and activities, and reduces severe exacerbations. Clinical trial registered with www.clinicaltrials.gov (NCT00496470).

Teacher imitation

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.
