Physicians' Knowledge, Attitudes, and Barriers Toward Clinical Trial Participation in Türkiye: A Cross-Sectional Survey and Implications for Oncology Research Capacity.
Article in Journal of multidisciplinary healthcare, 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
Background: Physicians influence clinical trial conduct and patient referral, yet country-specific evidence regarding their knowledge, attitudes, and perceived barriers in Türkiye remains limited. This evidence gap is especially relevant to oncology, where clinical trials are closely linked to therapeutic innovation and access to novel treatments. Objective: This study evaluated physicians' clinical trial knowledge, experience, attitudes, perceived barriers, and motivational factors, and identified variables associated with positive attitudes toward clinical research. Methods: A cross-sectional online survey was conducted between January 20 and March 7, 2025, targeting practicing physicians across Türkiye. Using a structured 23-item questionnaire, demographics, clinical trial experience, education, knowledge, attitudes, and perceived barriers were assessed. Descriptive statistics and ordinal regression analysis were performed. Results: Among 195 respondents (54.4% female; median age, 39 years), 61.0% had participated in a clinical trial. No knowledge of suspected unexpected serious adverse reaction terminology and Phase I/early-phase trials was reported by 56.4% and 26.7%, respectively, whereas 89.8% considered clinical trials essential for generating medical knowledge. Frequently reported barriers included lack of sponsors (89.3%) and financial constraints (83.1%). Greater clinical trial knowledge was associated with more favorable attitudes (β = 1.051, SE = 0.237, p < 0.001). Oncology physicians had higher prior clinical trial participation than non-oncology physicians (85.5% vs 49.6%, p < 0.001), including after multivariable adjustment (OR 3.46, 95% CI 1.37-8.74, p = 0.009). Conclusion: Physicians in Türkiye have favorable attitudes toward clinical trials but face important knowledge, logistical, and institutional barriers. Strengthening clinical research education and organizational support may improve physician engagement and contribute to oncology research capacity.
