The Guardian Science reports a possible lasting effect of baxdrostat

The Guardian Science reports that a small study found lower blood pressure persisted for up to two years in 14 patients who stopped taking baxdrostat after a course lasting six to 12 months. Just under a quarter came off all treatment and had normal blood pressure, but Mason Freeman says it is too early to know whether they were cured; a larger trial is under way. Baxdrostat is an aldosterone synthase inhibitor (ASI), a drug that suppresses aldosterone. The article describes primary aldosteronism as excess aldosterone from nodules or benign tumours on the adrenal glands, which raises blood pressure by prompting the kidneys to retain salt. The finding matters because, if the lasting effect is common, Freeman says treatment and diagnosis could change: patients might try an ASI first and avoid invasive diagnostic procedures and surgery if they respond. That possibility is not established by this small study. Morris Brown suspects reactive oxygen species may destroy cells that overproduce aldosterone, based partly on earlier mouse research; he says this proposed mechanism is being tested in the laboratory.

attribution — pass: The reading attributes the report to The Guardian Science. It assigns the cure caution and the diagnosis/treatment scenario to Mason Freeman, and the reactive-oxygen-species mechanism to Morris Brown. Each matches the article. The 'just under a quarter' figure is Brown's quoted statement, and the reading presents it inside the Guardian's report, which is acceptable.

Mason Freeman, a professor of medicine at Harvard University, who was involved in the work, said it was too early to say if some of the patients were cured

summary — pass: The reading explains baxdrostat, ASI, aldosterone and primary aldosteronism in plain language, and it keeps the small sample size and the larger trial. One smaller loss of force: Freeman said the approach is 'likely to dramatically change', but the reading says it 'could change'. The smallest repair is to quote his phrase directly. The conditional framing is still preserved, so meaning is not materially distorted. The question follows directly from the evidence.

If this effect is common and very persistent then the approach to diagnosing and treating these patients is likely to dramatically change

support — pass: The claims are grounded in the text: 14 patients, a course of six to 12 months, lower blood pressure up to two years later, just under a quarter off all treatment, a larger trial under way, and a mechanism being tested in the laboratory. The reading frames the possible benefit (avoiding invasive procedures and surgery) as Freeman's conditional scenario rather than an established fact. The word 'partly' in 'based partly on earlier mouse research' is a slight hedge, but it is harmless.

a larger trial was under way to find out
