Abstract

fetched live from OpenAlex

COPD is associated with increased risk of mortality and cardiopulmonary (CP) events. COPD patients with asthma have higher risk than with COPD alone. This study investigated all-cause mortality (ACM) and CP risks for budesonide/glycopyrrolate/formoterol fumarate (BGF) compared to MITT among patients with both COPD and asthma. This retrospective study used the Optum Clinformatics® Database. Patients were ≥40 years, ≥2 diagnoses for COPD, ≥1 baseline diagnosis for asthma, initiating BGF or MITT (10/1/2020–6/30/2023), ≥12 months baseline history prior to 1st fill of MITT or BGF (index), without prior triple therapy. Inverse propensity treatment weighting (IPTW) with Cox proportional hazards was used to assess outcomes of time to ACM and first CP event. 2755 BGF and 2732 MITT initiators were identified. After IPTW, patients were well balanced for all baseline characteristics (SMD<0.01). BGF initiators had a 23% lower risk of ACM (adjHR [95% CI]: 0.77 [0.61–0.97]) and 18% lower risk of CP events compared to MITT initiators (adjHR: 0.82 [0.73–0.93]) erj;66/suppl_69/PA1400/F1 F1 F1 . Among patients with COPD and asthma, BGF was associated with lower risk of all-cause mortality and cardiopulmonary events. This study provides real-world evidence for the reduction of these risks using BGF instead of MITT for COPD patients with asthma.

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.
