Ultrasound-guided thermal ablation in patients affected by Graves' disease: a systematic review and meta-analysis.

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
introductionUltrasound-guided thermal ablation (U-GTA) techniques, including radiofrequency ablation (RFA) and microwave ablation (MWA), have recently been proposed as minimally invasive alternatives to surgery or radioiodine (RAI) therapy for patients with Graves' disease (GD) who are unresponsive to antithyroid drugs. However, evidence supporting its effectiveness and safety remains limited.
methodsA PubMed/MEDLINE, Web of Science, and Scopus research updated until January 31, 2026, was performed. The review question was: What is the euthyroidism rate (outcome) one year after U-GTA (intervention) in Graves' disease (population)? Two reviewers independently conducted the study screening, data extraction, and risk of bias assessment. A random-effects model was adopted to pool the prevalence with corresponding 95% confidence intervals.
resultsFour studies comprising 82 patients (88% female) were included in the analysis. Approximately 2.4% of patients required levothyroxine replacement after U-GTA. Thyroid volume significantly decreased following treatment, and baseline thyroid volume was identified as a predictor of relapse in one study. A transient increase in anti-TSH receptor antibodies was observed one month after U-GTA, followed by a subsequent decline. No worsening or new onset of Graves' orbitopathy was reported. Post-procedural adverse events occurred in 6.1% of patients and were transient. At 12 months, pooled euthyroidism rate was 67.0% (95% CI 54-78), with low heterogeneity (I² = 0%). DISCUSSION: U-GTA appears to induce biochemical remission in approximately two-thirds of selected patients with persistent or relapsed GD, with a favourable short-term safety profile and preservation of thyroid function in most cases. However, remission rates remain lower than those typically reported for definitive surgical treatment, and current evidence is limited to small, non-randomized studies with relatively short follow-up. Larger prospective comparative trials with standardized protocols are required to define the role of U-GTA within current management strategies for GD.
