Clinical trial distribution across Africa reveals a continent of extreme internal inequality. A handful of nations — primarily Egypt, South Africa, and Kenya — host the vast majority of research activity, while dozens of countries with significant disease burdens have minimal or no trial presence. The per-capita analysis exposes further inequities: small nations with established research infrastructure (like Gambia, thanks to the MRC unit) can outperform giants like Nigeria on a population-adjusted basis. Understanding these patterns is essential for any strategy to build equitable, sovereign clinical research capacity across the continent.
