Age-stratified differences in asymptomatic primary hyperparathyroidism: a single-center cohort study from 2017 to 2024.
Article in Gland surgery, 2026. 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
Background: Primary hyperparathyroidism (PHPT) is increasingly diagnosed as asymptomatic due to routine biochemical screening. While parathyroidectomy (PTX) is the definitive treatment, age-specific management strategies for asymptomatic patients remain contentious, particularly in patients >50 years. Current evidence lacks detailed comparisons of disease characteristics and surgical outcomes across age-stratified asymptomatic cohorts. This study aims to bridge this information gap. Methods: This retrospective cohort study analyzed 199 asymptomatic PHPT patients who underwent PTX at Shanghai Sixth People's Hospital between 2017 and 2024. Data regarding demographics, biochemical parameters, imaging data, surgical details, complications and outcomes were collected and compared by age at diagnosis (≤50 or >50 years). Results: Among 199 patients who underwent PTX, 128 (64.3%) were >50 years old and 71 (35.7%) were ≤50. Patients in the younger cohort (≤50 years) exhibited significantly lower preoperative 25-hydroxyvitamin D levels (P<0.001), larger parathyroid adenomas (P=0.049), stronger correlations between adenoma volume and preoperative serum parathyroid hormone (PTH) and calcium levels (P<0.001), longer operative durations (P=0.01), and higher rates of endoscopic parathyroidectomy (EPTX) (P<0.001). Quadrant-level localization accuracy via ultrasonography was significantly higher in younger patients (85.5% Conclusions: Patients ≤50 years demonstrated superior preoperative localization accuracy, which was associated with larger tumor size. Patients >50 years exhibited a non-significantly lower trend in transient hypocalcemia. Both age cohorts achieved comparably high surgical cure rates, supporting the efficacy of PTX across age groups for asymptomatic PHPT.
