Why It Matters
AI/ML-augmented trial designs are emerging globally but barely present in Africa, risking a new digital divide in research methodology that could further marginalize the continent.
The Evidence 134 words · target 156
In the methodological architecture of African clinical research, does the pattern of ai & machine learning in trials reveal structural inequity in African research investment? This cross-sectional audit evaluated 23,873 African and 190,644 United States interventional trials registered on ClinicalTrials.gov through April 2026. Investigators computed the logistic growth rate parameter as the primary estimand using registry metadata for each nation. Africa registered 10 relevant trials compared to 1,436 in the United States, revealing an 144-fold absolute gap in research volume. Temporal analysis showed 17.1-fold growth in African trial registrations from 2000-2005 to 2021-2025, though the gap with high-income regions persisted. These results indicate that methodological capacity gaps limit the quality and impact of African clinical research output. Interpretation is limited by the use of a single registry and the absence of non-English trial databases.
