Assessing the accuracy of thyroid nodule risk-stratification tools in Hispanic and non-Hispanic patients.
Article in Journal of the Endocrine Society, 2026. 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
Context: Ultrasound risk categories (thyroid imaging, reporting, and data systems, TI-RADS), fine-needle aspiration cytology (Bethesda), and molecular classifiers guide thyroid nodule management. However, these tools may perform differently across populations due to differences in thyroid cancer characteristics among Hispanic patients. Objective: In this study, we compared the predictive performance of these tools in Hispanic vs non-Hispanic patients using surgical pathology as the gold standard. Methods: We performed a retrospective study of adult patients (≥18 years) evaluated for thyroid nodules from January 2023 to June 2024 at a tertiary academic medical center. Nodules were stratified using TI-RADS, Bethesda, and molecular testing. Malignancy was confirmed by final surgical pathology, and positive predictive value was assessed within diagnostic strata among resected nodules. Results: A total of 308 patients (421 nodules) were included in the analytic cohort, with 29.2% being Hispanic. Mean age was 54.3 ± 15.4 years in Hispanic patients and 58.8 ± 16.1 years in non-Hispanic patients ( Conclusion: Despite similar use of diagnostic tools, Hispanic patients had higher malignancy rates overall and within select diagnostic strata. These findings suggest variation in risk estimate performance across populations and support multicenter validation in diverse cohorts.
