Abstract
BACKGROUND: A limited number of studies have examined the age and sex differences, and potentially changing trends, in cardiac medication and procedure use in patients hospitalized with an acute coronary syndrome (ACS). METHODS: Using data from a large multinational study, we examined the age and sex differences, and changing trends (1999-2007) therein, in the hospital use of evidence-based therapies in patients hospitalized with an ACS using data from the Global Registry of Acute Coronary Events (n=50 096). RESULTS: After adjustment for several variables, in comparison with men below 65 years, patients in other age-sex strata had a significantly lower odds of receiving aspirin [odds ratios (ORs) for men 65-74, 75-84, and >or=85 years, women <65, 65-74, 75-84, and >or=85 years were 0.86, 0.84, 0.72, 0.80, 0.86, 0.68 and 0.46, respectively], angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers (ORs, 1.08, 1.01, 0,71, 0.83, 0.90, 0.89, and 0.63), beta blockers (ORs, 0.66, 0.52, 0.53, 0.67, 0.54, 0.53, and 0.52), statins (ORs, 0.72, 0.49, 0.29, 0.82, 0.68, 0.44, and 0.22), and undergoing coronary artery bypass graft surgery or a percutaneous coronary intervention (ORs, 0.79, 0.53, 0.21, 0.64, 0.57, 0.38, and 0.13) during their acute hospitalization. Age and sex differences in the receipt of these therapies remained relatively unchanged during the period under study. CONCLUSION: Although there were increasing trends in the use of evidence-based medications and cardiac procedures over time, important gaps in the utilization of effective cardiac treatment modalities persist in elderly patients and younger women.

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 it
