Lesion size and cystic morphology are key determinants of parathyroid hormone washout in primary hyperparathyroidism.

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
Purpose: Accurate preoperative localization of parathyroid adenomas is of great importance to ensure targeted and effective surgical treatment of primary hyperparathyroidism (PHPT). In this context, parathyroid fine-needle aspiration biopsy (FNAB) performed under ultrasound guidance plays a crucial role. This study aimed to evaluate the relationship between ultrasonographic features of parathyroid adenomas and parathyroid hormone washout (PTH-WO) values. Methods: Between January 2022 and August 2024, data from 128 parathyroid adenomas in 122 patients who were prepared for surgery due to PHPT and underwent ultrasound-guided FNAB along with PTH-WO testing were retrospectively evaluated. The obtained PTH-WO results were compared with B-mode and Doppler ultrasound findings. Results: In adenomas with a long axis greater than 10 mm and those containing cystic components, PTH-WO levels were found to be significantly higher (p = 0.005 and p = 0.02, respectively). Additionally, a positive correlation was identified between PTH-WO levels and the short and long axis dimensions of the adenomas. In contrast, no significant relationship was observed between PTH-WO levels and B-mode (grayscale) or Doppler (vascularity) ultrasound features. Conclusion: PTH-WO values vary according to the ultrasonographic dimensions of parathyroid adenomas and are measured at higher levels in cystic adenomas. Other ultrasonographic features do not significantly affect PTH-WO levels. Therefore, the size of the lesion should be taken into account when interpreting PTH-WO results.
