“There was no room for any errors in the way we gathered or reported the data. So, having the ability to have the data checked and validated by an independent assessor was key to our decision to use Silhouette. The ARANZ Medical team were great to work with and the Silhouette system was easy to use and provided accurate information – both of these elements played important roles in the success of our study.”
