Does Thyroid Dysfunction Have a Role in the Etiology of Vocal Fold Edema?
Article in Clinics and practice, 2025. 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/
objectivesPrevious studies have shown that hypothyroidism with myxedema may significantly affect the vocal folds. The aim of this study was to investigate thyroid dysfunction and other possible risk factors, including smoking, for the development of Reinke's edema (RE) in a group of men.
methodsSerum levels of thyroid-stimulating hormone (TSH), free thyroxine (fT4), and free triiodothyronine (fT3) were measured in a group of men with first occurrence or recurrent RE and in age- and gender-matched control subjects without laryngeal pathology. All participants completed a questionnaire on other possible etiologic factors for the development of RE, especially smoking. Risk factors were compared between the two groups. Levels of TSH and thyroid hormones were also compared between patients with recurrent disease and those with a first occurrence of RE.
resultsA total of 53 men with RE (mean age 53.82 years) and 45 controls (mean age 57.71 years) completed the study protocol. TSH and thyroid hormone levels were within the normal limits in all participants. Serum fT3 levels were significantly higher in patients with RE compared to controls (
conclusionsAn association between hypothyroidism and the development of RE was not confirmed. The significantly higher fT3 levels in patients compared to controls were still within the normal range and may reflect normal variation. Regression analysis of possible risk factors for RE showed the primacy of smoking.
