Ultrasound diagnosis of parathyroid adenomas mimicking normal lymph nodes: microvascular clues.

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: Ultrasound (US) is the preferred imaging modality for preoperative localization of primary hyperparathyroidism (PHPT). Parathyroid adenomas may be confused with normal lymph nodes on conventional US. This study aimed to explore the usefulness of microvascular flow imaging (MVFI) in differentiating parathyroid adenomas from normal lymph nodes and compare it with color Doppler flow imaging (CDFI). Methods: A total of 34 parathyroid adenomas that appeared peripherally hypoechoic and internally hyperechoic mimicking normal lymph nodes were identified in 34 patients with PHPT, and 34 cervical level III normal lymph nodes from 34 healthy controls were selected for comparison. The ability of CDFI and MVFI to detect the vascular characteristics of parathyroid adenomas were compared. Results: On CDFI, the detection rates of polar vessels, hilar vessels, and rich vascular in parathyroid adenomas were 44.1%, 8.8%, and 52.9%, respectively. These characteristics in normal lymph nodes showed detection rates of 2.9%, 38.2%, and 8.8%, respectively. On MVFI, the detection rates of polar vessels, hilar vessels, and rich vascular in parathyroid adenomas were 82.4%, 5.9%, and 94.1%, respectively. For normal lymph nodes, the detection rates of these characteristics were 5.9%, 76.5%, and 11.8%, respectively. Compared with CDFI, MVFI detected a significantly higher rate of polar vessels and rich vascularity in parathyroid adenomas (82.4% Conclusions: MVFI more frequently identified polar vessels and rich vascularity in parathyroid adenomas, as well as hilar vessels in lymph nodes, compared to CDFI. This suggests that MVFI may play a better role in differentiating parathyroid adenomas from lymph nodes, contributing to surgical planning in PHPT cases.
