*

Odds ratios are for risk of disease grade relative to the risk of not having cancer among patients who had a biopsy

**

Adjusted for age, race, PSA, DRE, previous biopsy, TRUS prostate volume, and family history of PC

PC=prostate cancer; BMI=body mass index (kg/m2); OR=odds ratio; CI=confidence interval
