Serum Vitamin D Levels in Autoimmune and Non-Autoimmune Hypothyroidism: A Retrospective Study from Jordan.
Article in Avicenna journal of medicine, 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: Vitamin D is a steroid hormone primarily produced in the skin. In Jordan, vitamin D deficiency is widespread among the population. This study aims to compare serum vitamin D levels between patients with autoimmune and non-autoimmune hypothyroidism. Methods: A retrospective observational study was conducted at the Jordanian Royal Medical Services in Jordan from January 2023 to November 2024. Data were gathered from the patient's medical records, including age, gender, vitamin D level, thyroid-stimulating hormone (TSH) value, free thyroxine (FT4) level, anti-thyroid peroxidase, and anti-thyroglobulin levels. Results: A total of 150 patients were included, aged 5 to 76 years, with a mean age of 39.2 years. The mean vitamin D level was 17.9 ng/mL, indicating widespread deficiency. There was no significant difference in vitamin D levels between patients with autoimmune and non-autoimmune hypothyroidism ( Conclusion: Serum vitamin D levels do not significantly differ between patients with autoimmune and non-autoimmune hypothyroidism, nor do they correlate with TSH levels. Further studies are needed to evaluate vitamin D status in these patient groups.
