Systematic review of benign thyroid enlargement as a rare cause of arterial compression: clinical presentations and outcomes.
Article in Endocrine connections, 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
The objective of this study is to systematically characterize the presentation, management, and outcomes of arterial complications secondary to benign thyroid enlargement, thereby improving clinical recognition and management of this rare entity. A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines across PubMed, Web of Science, Embase, and Scopus for studies published from January 1990 to February 2026. This review was registered with PROSPERO CRD420251156228. Studies describing arterial compression, displacement, stenosis, or occlusion attributable to benign thyroid pathology were included. Ten studies met the inclusion criteria, comprising 10 patients with a median age of 66 years, of whom 80% were female. Six patients presented with acute neurologic symptoms, including limb-shaking episodes and lateralized weakness, while the remainder exhibited subacute or chronic compressive complaints. Computed tomography with or without angiography was the primary diagnostic modality. The common carotid artery was involved in nine patients, including bilateral compression in two patients. Multinodular goiter was the most common pathology, with goiter sizes reaching up to 15 cm. Surgical management via thyroidectomy was performed in five patients, while the others were managed conservatively. Follow-up was documented in only five of the ten patients; in each of these, symptoms resolved without reported recurrence, while the remaining five reports contained no post-treatment follow-up data. In conclusion, benign thyroid enlargement is a rare but clinically significant cause of cervical arterial compression that can precipitate neurologic symptoms mimicking cerebrovascular disease. Cross-sectional imaging is essential for diagnosis, and both surgical decompression and conservative strategies were followed by symptom resolution in the cases with documented follow-up. Because the evidence base comprises ten single-patient reports with incomplete follow-up, no objective outcome measures, and no comparative data, certainty of evidence is very low, and these findings should be regarded as hypothesis-generating rather than as guidance for management.
