Restless legs syndrome and hashimoto's thyroiditis.
Article in Acta neurologica Belgica, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundIt has been hypothesized that an imbalance between thyroid hormones and dopaminergic activity may contribute to the development of Restless legs syndrome (RLS). This study aimed to evaluate the incidence and severity of RLS in patients with Hashimoto's thyroiditis compared to healthy controls, with a focus on the potential impact of thyroid hormone replacement therapy.
methodsA total of 120 consecutive patients, 80 with Hashimoto's thyroiditis (40 untreated, 40 under treatment) and 40 healthy controls, were included in the study. RLS symptoms were assessed based on the International Restless Legs Syndrome Study Group (IRLSSG) diagnostic criteria. Symptom severity was evaluated using the Restless Legs Syndrome Severity Rating Scale (RLS-SRS).
resultsRLS symptoms and RLS-SRS scores were significantly higher in patients with Hashimoto's thyroiditis compared to healthy controls (p < 0.01). The untreated group showed a significantly higher RLS incidence and symptom severity than both the treated group and controls (p < 0.001). No significant difference was observed between the treated Hashimoto's group and the control group. Additionally, RLS severity was associated with a longer duration of Hashimoto's disease (p = 0.03).
conclusionThe results of our study suggest that RLS is more prevalent and severe in patients with untreated Hashimoto's thyroiditis. Furthermore, thyroid hormone replacement therapy may have a protective role in reducing both the incidence and severity of RLS in this population.
