Two-way contingency tables comparing secreted frizzled-related protein 2S (SFRP-2) immunohistochemical scores (0/1, negative; 2/3, positive)
| Test | Histology | Score of SFRP-2 no. (%) | Score of SFRP-2 no. (%) |
|---|---|---|---|
| Histologically benign versus tumour (G3, G4 or G5) | Histologically benign (n = 699) | 161 (23) | 538 (77) |
| Chi-square, P < 0.0001 | Cancer (n = 902) | 696 (77) | 208 (23) |
| Gleason grade 5 versus Gleason grade 3 or 4 | Gleason grade <5 (n = 760) | 610 (80) | 150 (20) |
| Chi-square, P < 0.0001 | Gleason grade 5 (n = 144) | 58 (40) | 86 (60) |
| Histologically benign versus Gleason grade 3 | Histologically benign (n = 699) | 161 (23) | 538 (77) |
| Chi-square, P < 0.0001 | Gleason grade 3 (n = 439) | 371 (85) | 68 (15) |
