Abstract

fetched live from OpenAlex

UNLABELLED: Excessively high and low achieved blood pressure (BP) may be associated with a bad outcome in patients with coronary artery disease, the J curve phenomenon. The effect of BP changes from baseline in relation with the subsequent risk of stroke and myocardial infarction (MI) is unknown. Of the 25 620 patients randomized in the Ongoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial (ONTARGET) study, we selected 19 102 patients with coronary artery disease at baseline. BP at entry was 141/82 mm Hg, and its average decrease during follow-up was 7/6 mm Hg. BP entered the analysis as time-varying variable modeled with restricted cubic splines. After adjustment for several potential determinants of reverse causality, a change in BP from baseline by -34/-21 mm Hg (10th percentile) was associated with a lesser risk of stroke without any significant increase in the risk of MI. A rise in systolic/diastolic BP from baseline by 20/10 mm Hg (90th percentile) was associated with an increased risk of stroke, whereas the risk of MI increased with systolic BP and not with diastolic BP. In conclusion, in patients with coronary artery disease and initially free from congestive heart failure, a BP reduction from baseline over the examined BP range had little effect on the risk of MI and predicted a lower risk of stroke. An increase in systolic BP from baseline increased the risk of stroke and MI. The relationships of BP with risk were much steeper for stroke than for MI. A treatment-induced BP reduction over the explored range seems to be safe in patients with coronary artery disease. CLINICAL TRIAL REGISTRATION URL: http://www.clinicaltrials.gov.

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.
