One of clients (Top 5 CRO) had already been using nQuery Sample Size Calculator successfully for 12 years, at multiple locations worldwide. One of their lead statisticians contacted us with a specific issue they were trying to solve. The problem was centered around the creation of randomization lists using mixed block sizes in clinical trials. The lead statistician felt that there was a possibility of introducing bias when using fixed block sizes in clinical trials.
The company had attempted to develop SAS macro's to solve the problem, but found that these macro's had serious limitations, were cumbersome to use and most importantly could not accommodate the mixed block size design.
We worked closely with this CRO to develop the required mixed block sizes functionality including:
This fully validated functionality was developed quickly and rolled out to the CRO's userbase within 4 months. As a result of this cooperation with a world-class CRO, this much-needed functionality is now available in nQuery and is used and appreciated by our other CRO clients.
