PRIMARY outcome

Timeframe: At the time of biopsy

Population: A total of n=466 subjects have valid and reportable PCA3 Scores and disease status (determined by biopsy result), and who were 50 years of age or older.

The likelihood of positive biopsy was determined by the PCA3 Score expressed as a binary categorical variable: PCA3 Score \>=25 was positive, PCA3 Score \<25 was negative
