PSA PFS was defined as the interval from trial Day 1 to the earlier of a PSA progression or death from any cause; otherwise, PSA PFS was censored on the date of the last PSA measurement.
If a participant had no baseline or post-baseline PSA measurement and a vital status of alive or known, PSA PFS was censored at trial Day 1.
The median was estimated using the Kaplan-Meier method and the 95% confidence interval was estimated using the method by Brookmeyer and Crowley.
