Felodipine–Metoprolol Combination Tablet: Maintained Health-Related Quality of Life in the Presence of Substantial Blood Pressure Reduction
Bibliographic record
Abstract
BACKGROUND: Most treated hypertensive patients do not achieve adequate blood pressure (BP) control. Initiating therapy with two drugs has been suggested when BP is >20/10 mm Hg above goal. To ensure patients' compliance, such treatment needs to be well tolerated and must not compromise health-related quality of life (HRQL). The primary objective of this study was to compare the effects on HRQL of initiating treatment with felodipine + metoprolol (F+M) fixed combination tablets, or enalapril (E), or placebo (P). METHODS: A total of 947 patients of both sexes with primary hypertension (diastolic BP 95 to 110 mm Hg), aged 20 to 70 years, participated in this randomized, double-blind, parallel group, 12-week, multicenter trial. Treatment was initiated with F+M 5 + 50 mg, or E 10 mg, or P. Doses were doubled after 4 or 8 weeks if diastolic BP was >90 mm Hg. The HRQL was measured at baseline and at the last visit using two validated questionnaires: the Psychological General Well-being Index (PGWB) and the Subjective Symptom Assessment Profile (SSA-P). Office BP was measured at trough, that is, 24 h after the previous dose. RESULTS: The HRQL was high at baseline and generally well maintained during the study. For example, the mean (SD) PGWB total score was 104 (16) at baseline and 105 (16) at 12 weeks in all three treatment groups. The BP reductions after F+M (18/14 mm Hg) and E (12/9 mm Hg) were significantly greater than after P (7/7 mm Hg), and the reduction after F+M was significantly greater than after E. CONCLUSIONS: The HRQL is maintained in the presence of substantial BP reduction during antihypertensive treatment with F+M fixed combination tablets.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
