Examining Recruitment and Retention Strategies for Underserved Populations in Thyroid Cancer Clinical Trials: A Cross-Sectional Analysis.
Article in Laryngoscope investigative otolaryngology, 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
Objectives: Thyroid cancer incidence has risen sharply in the US, with disparities in diagnosis and treatment outcomes disproportionately affecting marginalized populations. Despite mandates for diversity in clinical trials, underrepresentation of these groups remains a critical barrier to equitable health outcomes. This study evaluates recruitment and retention strategies in thyroid cancer trials and highlights areas for improvement to enhance inclusivity and generalizability. Methods: This cross-sectional analysis examined the reporting of recruitment and retention strategies for historically marginalized populations in thyroid cancer clinical trials. Following PRISMA guidelines, we searched MEDLINE, Embase, and Cochrane databases for trials published between 2018 and 2023. Eligible studies assessed thyroid cancer treatment interventions and were conducted in locations with a national or multinational Ethnic Fractionalization Index (EFI) of ≥ 0.3. Data extraction included trial characteristics and reporting of recruitment and retention practices. Descriptive analyses were performed using Stata. Results: Of 708 articles identified, 28 clinical trials met inclusion criteria. None reported recruitment or retention strategies targeting underrepresented populations, nor established diversity goals. The absence of such strategies highlights persistent gaps in addressing the needs of marginalized groups in thyroid cancer research. Conclusion: The lack of effective recruitment and retention strategies in thyroid cancer trials perpetuates the underrepresentation of marginalized populations, limiting the generalizability of findings. To address these disparities, clinical trials must adopt inclusive methodologies and transparent reporting practices, supported by policy changes and stronger enforcement of diversity mandates. These steps are essential for ensuring equitable health outcomes and advancing the quality of thyroid cancer research. Level of Evidence: 3.
