Multivariate Cox regression model on timing to biochemical recurrence and its association with type of probe.

Variable	Hazard ratio	95% confidence interval	p
V-Probe® vs. fixed-size ice probe	0.78	0.45–1.32	0.344
Preoperative PSA	1.09	1.03–1.15	0.003
Neoadjuvant ADT	1.65	1.07–2.54	0.022
Preoperative Gleason score	1.03	0.81–1.32	0.811
Preoperative ≥cT2 compared to cT1	1.56	1.03–2.37	0.035

ADT = androgen deprivation therapy; cT1 = clinical stage T1 [non-palpable disease]; cT2 = clinical stage T2 [organ-confined palpable disease]; PSA = prostate-specific antigen.
