A study demonstrating the general usability and absence of any major issues with respondents completing the SGRQ on the
tablet device was conducted by United BioSource Corporation (UBC) on CRF Health’s behalf and the results were summarized in
a report.

The electronic version of the SGRQ provides clinical trial managers more flexibility in designing trials along with the many other
benefits of using ePRO, including improved compliance, higher quality data, and more efficient clinical trials.

Mary Briggs, VP Global Sales & Marketing, commented, "Gaining these types of approvals from instrument authors and
partnering with valued PRO thought leaders to expand the use of technology in clinical trials are two examples of CRF Health’s
strategy to offer the best services in the global ePRO marketplace."
