Logistic analysis of variables associated with cancer detection in all cases.

Variables	Univariate			Multivariate
	OR	95% CI	P value	OR	95% CI	P value
Age	1.08	1.04–1.13	<0.0001	1.02	0.97–1.08	0.343
PSA	1.09	1.05–1.14	<0.0001	0.93	0.90–1.00	0.048
PV	0.97	0.95–0.98	<0.0001
PSAD 0.1 increase	1.87	1.53–2.36	<0.0001	2.08	1.60–2.76	<0.0001
TT	1.12	0.92–1.38	0.274
FT	0.84	0.76–0.92	0.0001	0.99	0.86–1.14	0.917
%FT 0.01 increase	0.92	0.89–0.96	<0.0001	0.93	0.89–0.98	0.0042

When treating PSAD and %FT as continuous predictors, the odds ratio have been computed for a 0.1 increase in PSAD levels and a 0.01% increase in %FT levels. P value was calculated by likelihood ratio test.

CI, confidence interval; FT, free testosterone; %FT, percent free testosterone; OR, odds ratio; PSA, prostate-specific antigen; PSAD, PSA density; PV, prostate volume; TT, total testosterone.
