Angiotensin Converting Enzyme Inhibitor Dialyzability and Outcomes in Older Patients Receiving Hemodialysis
Bibliographic record
Abstract
BACKGROUND/AIMS: Some angiotensin converting enzyme (ACE) inhibitors are efficiently removed from circulation by hemodialysis ('high dialyzability'), whereas others are not ('low dialyzability'). In patients receiving hemodialysis, this may influence the effectiveness of ACE inhibitors. METHODS: Using linked healthcare databases we identified older patients receiving chronic hemodialysis who filled new ACE inhibitor prescriptions. The low dialyzability group (n = 3,369) included fosinopril and ramipril. The high dialyzability group (n = 5,974) included enalapril, lisinopril, and perindopril. The primary outcome was all-cause mortality within 180 days of first ACE inhibitor prescription. RESULTS: There were 361 deaths among 5,974 patients (6.0%) prescribed with low dialyzability ACE inhibitors and 179 deaths among 3,369 patients (5.3%) prescribed with high dialyzability ACE inhibitors (relative risk 1.1, 95% CI 0.9-1.3, p = 0.6). CONCLUSION: In this study of older patients receiving hemodialysis, the dialyzability of ACE inhibitors was not associated with mortality or cardiovascular outcomes.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
