US features of normal parathyroid glands: a comparison with metastatic lymph nodes in thyroid cancer.
Article in Ultrasonography (Seoul, Korea), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
purposeThis study aimed to determine the ultrasound (US) features of normal parathyroid glands (PTGs) and to evaluate whether normal PTGs can be differentiated from metastatic lymph nodes (LNs) in thyroid cancer.
methodsThis retrospective study included 10 normal PTGs and 95 metastatic LNs from thyroid cancer showing suspicious US features. The echogenicity, echotexture, echogenic foci (calcifications), cystic change, abnormal vascularity, size, shape, and location were retrospectively assessed and compared between normal PTGs and metastatic LNs.
resultsThe echogenicity of normal PTGs was significantly different from that of metastatic LNs (P<0.001). Normal PTGs exhibited marked hyperechogenicity (100%), homogeneous echotexture (80%), focal intraglandular hypoechogenicity (20%), ovoid shape (90%), and focal cystic change in one case (10%). The echogenicity of metastatic LNs was markedly hyperechoic (0%), moderately hyperechoic (15.8%), mildly hyperechoic (53.7%), and hypoechoic (28.4%). The size and long axis/short axis ratios of normal PTGs were significantly smaller and larger than those of metastatic LNs (P<0.01 and P=0.022, respectively).
conclusionMarked hyperechogenicity was found only in normal PTGs, and small, ovoid, markedly hyperechoic structures in the paramedian central neck characterized normal PTGs. Normal PTGs may be differentiated from metastatic LNs in thyroid cancer.
