Base Multivariate Cox Model Analysis
| Variable | Effect | HR (95% CI) | Median P | |
|---|---|---|---|---|
| Age | 0.74 | 2.10 | (1.52, 2.91) | <.001 |
| HV | 0.54 | 1.72 | (1.23, 2.41) | .002 |
| SUVpeak | 0.66 | 1.93 | (1.18, 3.17) | .006 |
| TBmax | −0.50 | 0.61 | (0.39, 0.96) | .023 |
The base multivariate Cox model was comprised of 4 conventional variables, showing predictor effects, associated hazard ratio (HR) with associated 95% confidence interval (CI), and bootstrap median P-values obtained from 1000 bootstrap resamples. All 4 variables are significant at the 5% level; P-values in bold indicate significance after bonferroni correction (P < .005). This model has a concordance index of 0.722.
