Differences in bilaterally distribution of HGPIN, ASAP, and prostate cancer diagnosed at the first biopsy between African American and Caucasian.

	African American	Caucasian	P value
	n/N	n/N
HGPIN	41/90 (45.6%)	25/75 (33.3%)	0.004^a
ASAP	7/30 (23.3%)	1/21 (4.8%)	0.119^b
Prostate cancer	295/479 (61.5%)	97/274 (35.4%)	<0.0001^c

n = number of bilateral distribution; N = total cases with available information on pathology distribution; ^a: Ratio = 2.51, 95% CI: 1.3–4.9; ^b: Odds Ratio = 6.08, 95% CI: 0.6–143.3; ^c: Odds ratio = 2.93, 95% CI: 2.1–4.
