Treatment alteration scores - these should be present in the database for all post-baseline biopsies and so can be summarized over all subjects. Note that these are provided on both a per-core and a per-biopsy (overall) basis. For analysis purposes use the overall values (OVNTASC=overall nuclear treatment alteration score (0-3), OVATASC=overall architectural treatment alteration score (0-3), and overall treatment alteration score (0-6) which is OVNTASC+OVATASC) (Matt's e-mail: Tue, 16 Aug 2005 09:56:58 -0400).
