- Clinical trial planning teams

- The recruitment tool offers varying site performance and a cumulative recruitment graph; drug supply includes whole bottles and overage.
Field notes
The site organizes clinical-trial planning around four operational questions: how many patients to screen, how recruitment may accumulate, how long key study milestones may take, and how much oral drug supply to prepare. Its recruitment description distinguishes a basic estimate from a forecast that varies site performance, while the supply calculator is framed around arms or groups, whole bottles, and overage. The homepage also explicitly tells users to compare outputs with the protocol and operational plan.
