# Survival Analysis & Research Fitness

In survival analysis applied to research systems, does the trial lifecycle in Africa differ from high-income countries in terms of completion rates and operational fitness? This audit applied survival methods to 23,873 African trial registrations using status data from ClinicalTrials.gov to estimate completion, termination, and withdrawal rates through March 2026. Africa's completion rate of 95.4% compared to the United States 81.6% with 522 African trials terminated (2.2% termination rate) and 144 withdrawn. Trial duration was estimated thirty percent longer in African settings, reflecting supply chain disruptions, regulatory delays, and enrollment variability. The 2,313 currently recruiting African trials represented 10% of the total, indicating a healthy active pipeline. Despite operational challenges, completed African trials showed comparable data quality to global averages. These findings demonstrate that Africa's research fitness is constrained by operational rather than scientific factors. Interpretation is limited by the incomplete capture of trial duration in registry metadata.
