| Factor | Statistic | d.f. | F(d.f.1,d.f.2) | P-value |
|---|---|---|---|---|
| Treated with DAiS | 0.91 | 1 | 1.01(15, 159) | 0.44 |
| Bad performance | 0.85 | 1 | 1.83(15, 159) | 0.03 |
| Metastatic disease | 0.87 | 1 | 1.59(15, 159) | 0.08 |
| PSA normalised | 0.89 | 1 | 1.30(15, 159) | 0.21 |
Abbreviations: DAiS=Dexamethasone, Aspirin, and immediate addition of Diethylstilbestrol; d.f.=degrees of freedom; PSA=prostate-specific antigen.
