Amlodipine Added to Quinapril vs Quinapril Alone for the Treatment of Hypertension in Diabetes: The Amlodipine in Diabetes (ANDI) Trial
Bibliographic record
Abstract
This randomized, comparative, parallel-group trial investigated strategies of blood pressure (BP)-lowering in patients with diabetes and hypertension. Patients not reaching goal BP (<130/80 mm Hg) after 4-week open-label treatment with quinapril 20 mg/d (n=374) received 40 mg/d quinapril (n=167) or 20 mg/d quinapril plus amlodipine besylate (5 mg/d; n=162) for 6 weeks. Patients receiving combination therapy vs monotherapy had significantly greater reductions in mean +/- SE sitting systolic BP (9.9+/-1.0 mm Hg vs 4.3+/-1.1 mm Hg; P<.001) and diastolic BP (6.5+/-0.6 mm Hg vs 2.7+/-0.6 mm Hg; P<.001). No significant differences between groups were observed in percentage of patients achieving goal BP (10.1% with combination therapy vs 8.2% with monotherapy). A clinically neutral effect was observed on high-sensitivity C-reactive protein in both groups. Treatments were well tolerated; fewer than 3% of patients in any group discontinued due to treatment-emergent or treatment-related adverse events. In diabetic hypertensive patients, 20 mg/d quinapril plus 5 mg/d amlodipine besylate was a more effective BP-lowering strategy than monotherapy with 40 mg/d quinapril.

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.
