Abstract
BACKGROUND: Eplerenone is claimed to be a more selective blocker of the mineralocorticoid receptor than spironolactone being associated with fewer antiandrogenic side-effects. We compared the efficacy, safety and tolerability of eplerenone versus spironolactone in patients with hypertension associated with primary aldosteronism. METHODS: The study was multicentre, randomized, double-blind, active-controlled, and parallel group design. Following a single-blind, placebo run-in period, patients were randomized 1: 1 to a 16-week double-blind, treatment period of spironolactone (75-225 mg once daily) or eplerenone (100-300 mg once daily) using a titration-to-effect design. To be randomized, patients had to meet biochemical criteria for primary aldosteronism and have a seated DBP at least 90 mmHg and less than 120 mmHg and SBP less than 200 mmHg. The primary efficacy endpoint was the antihypertensive effect of eplerenone versus spironolactone to establish noninferiority of eplerenone in the mean change from baseline in seated DBP. RESULTS: Changes from baseline in DBP were less on eplerenone (-5.6 ± 1.3 SE mmHg) than spironolactone (-12.5 ± 1.3 SE mmHg) [difference, -6.9 mmHg (-10.6, -3.3); P<0.001]. Although there were no significant differences between eplerenone and spironolactone in the overall incidence of adverse events, more patients randomized to spironolactone developed male gynaecomastia (21.2 versus 4.5%; P=0.033) and female mastodynia (21.1 versus 0.0%; P=0.026). CONCLUSION: The antihypertensive effect of spironolactone was significantly greater than that of eplerenone in hypertension associated with primary aldosteronism.

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
