Davidson: Similar to the phrase, “Happy wife, happy life,” if you have happy sites and sites that are engaged and get through the study startup process, that hopefully translates to their ability to enroll patients, and also not just enroll patients, but to reduce the compliance issues that they're going to have throughout the study. If you can focus on training, if you can focus on engaging with that site and study startup, in addition to the conduct part of the study, then hopefully that translates into better quality patient enrollment.
