Description

A workgroup will be convened to modify the TreeExtraction code and TreeScan software to allow for differential follow-up time and making the searching risk window parameters more flexible. The HPV4 vaccine will serve as the test case for the new capability, and will be run on internal test data for two follow-up periods: 6 months and 12 months.
