Ectopic thyroid tissue implantation associated with hyperthyroidism after endoscopic thyroidectomy: a case report.
Article in Frontiers in surgery, 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
Background: Needle track implantation is a rare complication of endoscopic surgery. This appears to be the first reported case of ectopic thyroid tissue implantation in the anterior chest wall following endoscopic thyroidectomy, accompanied by hyperthyroidism. Case description: The patient underwent endoscopic thyroidectomy for a 5 cm left thyroid adenoma. Within one year postoperatively, she noted a chest wall mass extending from the left subclavicular region to the line connecting the left nipple, accompanied by hyperthyroidism. Following treatment with antithyroid drugs, thyroid function was well controlled and the chest wall mass ceased to enlarge. Pathological examination confirmed the left anterior chest wall mass as ectopic thyroid tissue. Conclusions: This case highlights not only the risk of tissue fragment dissemination following endoscopic thyroidectomy but also indicates that ectopic thyroid tissue, under favorable microenvironmental conditions, can preserve follicular structure and may be involved in metabolic activity.
