Cardiovascular Morbidity in Patients Undergoing Successful Surgery for Primary Hyperparathyroidism.
Article in Clinical endocrinology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveAlthough previous studies have shown reduced cardiovascular events following parathyroidectomy (PTX), it is unclear whether this extends to contemporary patients diagnosed and treated with milder disease than previously. The aim of this nation-wide study was to determine the effect on cardiovascular events after PTX, and to comprehensively evaluate cardiovascular disease manifestations in patients with primary hyperparathyroidism, (pHPT).
designThe cohort consisted of 5009 patients who underwent PTX and were identified from the Scandinavian Quality Register for Thyroid, Parathyroid and Adrenal Surgery. Patients were matched with 14,983 population controls.
methodsData was linked with the National Patient and Death Registries. Incidence rate ratios (IRRs) were estimated before and after PTX for recurrent events of acute myocardial infarction, stroke, transient ischemic attack (TIA), and first-onset diagnoses of coronary artery disease, heart failure, aortic and mitral valve stenosis, carotid artery stenosis, peripheral artery disease, and aortic aneurysm (AA). Serum calcium and gland weight were analysed as predictors.
resultsTIA was increased in patients pre-and postoperatively with a peak 1-4 years before PTX (IRR: 2.06, CI 95%: 1.31-3.25). The incidence rates for acute myocardial infarction and stroke were not increased pre- and postoperatively. Mitral valve stenosis (IRR: 3.22, 1.51-6.85), and heart failure (IRR: 1.37, 1.11-1.67) were increased preoperatively, but not postoperatively. AA was increased pre- and postoperatively.
conclusionsThe incidence rates for mitral valve stenosis and heart failure were increased preoperatively in patients with pHPT, normalizing after surgery. In contrast, the incidence of TIA and AA remained elevated postoperatively.
