Optimizing Parathyroid Localization in Real Life: The Role of Expert-Performed Ultrasonography.
Article in Clinical endocrinology, 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
objectiveTo evaluate the accuracy of expert-performed ultrasonography (US) for preoperative localization in minimally invasive parathyroidectomy (MIP) compared with community US and other imaging modalities. STUDY
designRetrospective cohort study.
settingTertiary referral center for endocrine surgery.
methodsA retrospective, single-center diagnostic accuracy study of 227 patients with primary hyperparathyroidism who underwent surgery and pre-operative imaging by a dedicated neck radiologist (expert US). Sensitivity, specificity, and positive predictive value (PPV) were calculated, and were compared to other imaging modalities including community US, 99mTc-MIBI, SPECT-CT and 4DCT.
resultsExpert US showed high sensitivity (89%), specificity (98%), and PPV (95%), correctly localizing adenomas in 89% of cases. It outperformed the sensitivity and specificity of community US (50%/95%), MIBI (75%/95%), SPECT-CT (82%/96%) and 4D-CT (52%/94%), respectively, particularly in atypical cases like ectopic adenomas (25% prevalence) and multiglandular disease (6% prevalence).
conclusionsExpert-performed US should be considered the primary imaging modality for guiding MIP. Surgeons should consider referring patients to an expert ultrasonographer in cases of suspected ectopic adenoma, presence of multiglandular disease, before referring to 4D-CT scans or when considering bilateral neck explorations.
