Key Finding
African trials showed an estimated protocol completeness of fifty-eight percent versus eighty-seven percent for the United States, a gap reflecting resource constraints rather than researcher capability.

Why It Matters
African trial protocols show lower granularity and completeness compared to global standards. More metadata fields are missing, SPIRIT guideline compliance is partial, and the level of methodological detail is consistently lower. This is not a reflection of African researcher capability but of resource constraints: writing detailed protocols requires time, training, and institutional support that many African centres lack.

In protocol quality assessment, does the granularity and completeness of African trial protocols on ClinicalTrials.gov meet global standards for research transparency? This audit evaluated optional reporting fields, outcome specifications, and methodology descriptions for 23,873 African and 190,644 United States trials through March 2026. Investigators reported a protocol completeness score based on the proportion of populated optional metadata fields as the primary estimand. African trials showed an estimated protocol completeness of fifty-eight percent versus eighty-seven percent for the United States, a gap reflecting resource constraints rather than researcher capability. SPIRIT guideline compliance was partial in most African registrations, with sample size justification and statistical analysis plan details frequently missing. The 13,918 completed African trials showed higher protocol completeness than uncompleted trials, suggesting that better-documented protocols predict successful execution. These findings identify protocol granularity as both a quality marker and a potential intervention target for improving African research outcomes. Interpretation is limited by the assessment of protocol quality from registration metadata rather than full protocol documents.
