Thank you, Madam Chair.
And thank you to the witnesses for being here today.
My first question is to Dr. Vendittoli with regard to the replacements of any prosthetic limb. What would you suggest is a sufficient test period for a new device, and should it be tested against the ones that are already on the market to ensure that we're not going from bad to worse? It seems to me as though we've heard evidence before that we don't compare what's already on the market with what we're introducing into the market. Do you have any comments on that?
