Abstract
BACKGROUND: The purpose of this study was to evaluate the long-term efficacy of adrenalectomy on blood pressure control in patients with primary hyperaldosteronism (HA), and to analyse the cost of adrenalectomy compared with non-surgical management of HA over the patient's lifetime. METHODS: All patients who underwent an adrenalectomy for HA were recalled to the endocrine surgical clinic. Data gathered included blood pressure, aldosterone : renin ratios and medication. Total costs for adrenalectomy and ongoing medications were compared with the estimated costs of lifelong medical therapy alone. RESULTS: Twenty-four adrenalectomies were performed for HA, with one death. The mean follow-up was 42 (range 13-97) months. Long term, there was a significant decrease in both the mean diastolic and systolic blood pressure. The aldosterone : renin ratio decreased in 21 patients. Of these patients, 20 were either off all antihypertensives (eight) or had a reduction in medication (12). An increased aldosterone : renin ratio occurred in two patients, both of whom required an increase in antihypertensive medication. Using the predicted life expectancy, the mean estimated cost savings over the lifetime of each patient undergoing adrenalectomy compared with medication alone was Canadian $31 132. CONCLUSION: Adrenalectomy for HA resulted in significant long-term reduction in blood pressure. Adrenalectomy for HA is a significantly less expensive than long-term medical therapy alone.

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
