Male	37 (60)	25 (61)
Age (years), median (range)	67 (21–86)	76 (44–86)	0.007
Patient effective diameter* (cm), median (range)	44 (23–59)	40 (27–52)	0.079
Tumor size* (cm), median (range)	3 (1.0–5.4)	3 (1.5–5.0)	0.409
Number of cryoprobes, median (range)	6 (1–11)	6 (3–11)	0.609
Ancillary procedure performed, n (%)			0.953
Yes	20 (32)	13 (32)
No	42 (68)	28 (68)
Number of scans, median (range)	27 (14–53)	26 (13–41)	0.518

The data is presented as n (%), unless otherwise noted. The p values from the Pearson chi-square test (categorical variables) and the Wilcoxon Mann-Whitney (rank-sum) test (continuous) comparisons between the two groups are provided. Significance was taken if p < 0.05.

^*Patient effective diameter and tumor size were calculated according to Nguyen et al. (23).
