Why It Matters
African trials take longer to publish than trials from other regions, creating a delay penalty that means African evidence arrives too late to influence treatment guidelines.
The Evidence 130 words · target 156
In the governance and sovereignty of African clinical trials, does the pattern of publication lag penalty 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 Kaplan-Meier cumulative registration curve as the primary estimand using registry metadata for each nation. Africa registered 3,515 relevant trials compared to 159,433 in the United States, revealing an 45-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 findings demonstrate that structural governance deficits perpetuate research dependency and undermine African sovereignty over clinical evidence. Interpretation is limited by reliance on ClinicalTrials.gov alone, which may undercount locally registered African studies.
