Table 1. Univariate Model of MAOA Expression and Post-Therapy Biochemical Relapse.

Risk Factors	Hazard Ratio	P-value	95% CI
Gleason Grade*	2.02	0.014	1.15–3.56
Age	1.65	0.464	0.43–6.27
Baseline PSA	1.01	0.671	0.97–1.05
MAOA Expression Change * †	1.66	0.027	1.06–2.59

*p<0.05

^†MAOA expression in pre-treatment and post-treatment samples was measured by a quantitative real-time PCR. Expression changes were measured by cycle threshold difference (▵CT) of MAOA between post-treatment and pre-treatment samples.
