Parameter | 9181 | 9182 | |
Coefficient^{b} | 24.48 | 15.54 | |
SE | 7.32 | 4.0 | |
P | 0.0008 | 0.0001 | |
No. of patients | 137 | 233 | |
No. of deaths | 125 | 188 | |
Model LR^{c} | 28.7 | 71 |
^{a} Both models also included the level of PSA as the natural log (PSA), and the coefficients for this variable were 0.221 and 0.274, respectively; that is, the level of log (PSA) was given greater weight in the results for protocol 9182.
^{b} The coefficient is b2 of Eq. C ; the SEs refer to the expected variance in the estimates of the coefficients; and the Ps indicate the significance of the associations between rva and survival time in these three groups of patients.
^{c} LR, overall likelihood ratio.
