Schematic illustration of the blood centrifugation process, highlighting the minimum radius (×1 mm), average radius (×2 mm), and maximum radius (×3 mm). It is important to note that the relative centrifugal force (RCF) calculation is higher for ×3 mm than ×1 mm. Additionally, for studies that use small tubes and low amounts of animal blood and for those using a commercial centrifuge to produce PRF, the authors should consider the average radius (×2 mm) to provide the RCF in their methods.
