From: Concept and development of an interactive tool for trial recruitment planning and management
Assumption | Trial recruitment context | Assumption holds |
---|---|---|
Events taking place during one interval do not affect the next | Each recruitment is independent of the next | Yes |
Events take place one at a time | Patients are recruited individually, and recruitment data is recorded one at a time | Yes |
The average rate of events remains constant | The assumption has been challenged by Williford et al. [27], but numerous other sources support the assumption [26, 28, 29] | Yes |
