Evaluating the role of resistive index in pediatric Hashimoto's thyroiditis diagnosis and the impact of vitamin D treatment on resistive index.
Article in BMC pediatrics, 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
objectivesThyroid ultrasonography combined with color Doppler imaging represents one of the most reliable and non-invasive tools for assessing patients with Hashimoto’s thyroiditis. Growing evidence suggests that vitamin D deficiency contributes to the pathophysiology of this autoimmune disorder and may influence its progression toward hypothyroidism. This study aimed to explore the role of ultrasonography and color Doppler evaluation in children with Hashimoto’s thyroiditis and to determine the effect of vitamin D supplementation on resistive index values, as well as on serum thyroid hormone and antibody levels. MATERIALS AND
methodsEighty-four children were enrolled in this study, consisting of 45 diagnosed with Hashimoto’s thyroiditis and 39 age- and sex-matched healthy controls. In all participants, serum concentrations of 25-hydroxyvitamin D, calcium, phosphorus, alkaline phosphatase, thyroid hormones, and thyroid antibodies were analyzed. Both groups underwent grayscale ultrasonography and color Doppler evaluation of the thyroid gland. The patient group received oral vitamin D supplementation at approximately 2,000 IU daily. After two months of treatment, all biochemical and sonographic assessments were repeated.
resultsPatients with Hashimoto’s thyroiditis demonstrated significantly higher grayscale ultrasonography grades compared with controls. Free thyroxine and vitamin D levels were notably lower among patients. Following vitamin D supplementation, anti-thyroid peroxidase antibody titers decreased significantly, accompanied by a statistically meaningful reduction in resistive index values in the right, left, and overall thyroid lobes.
conclusionAlthough the resistive index alone does not appear to be a reliable diagnostic indicator for Hashimoto’s thyroiditis, vitamin D supplementation was associated with reductions in both resistive index values and anti-thyroid peroxidase antibody levels. Further controlled trials including untreated patients are warranted to confirm these findings.
