Table 4 Comparison of whole-body bone SPECT/CT results between PSA doubling time classes according to trigger PSA classes (p = 0.01 for global interaction)
PSA ≤10 ng/ml, N = 87 | ||||
Bone SPECT/CT result | Negative (N = 74) | Positive (N = 13) | OR (CI95) | p |
PSAdt > 6 months | 49 (92.5) | 4 (7.5) | reference | 0.03 |
PSAdt ≤6 months | 25 (73.5) | 9 (26.5) | 4.4 (1.1–21.2) | |
PSA > 10 ng/ml, N = 28 | ||||
Bone SPECT/CT result | Negative (N = 14) | Positive (N = 14) | OR (CI95) | p |
PSAdt > 6 months | 4 (66.7) | 2 (33.3) | reference | 0.32 |
PSAdt ≤6 months | 10 (45.5) | 12 (54.5) | 2.4 (0.3–30.9) | |
