Which products were compared with Arista AH in the study?

• A. Arista AH vs. Avitene
• B. Floseal and Surgiflo not compared
• C. Arista AH vs. Floseal and Surgiflo
• D. Arista AH vs. Gelfoam and Avitene

Answer: (C)

Understanding which products were used as comparators alongside Arista AH in the study helps you see how the test was set up. The study evaluated Arista AH against two established hemostatic agents, Floseal and Surgiflo, to see how it stacks up against these two options. The other products mentioned in the choices, Avitene or Gelfoam, were not used as comparator arms in this study, so they don’t describe what was actually tested. So, the correct description is that Arista AH was compared with both Floseal and Surgiflo.
