Univariate and multivariate survival analyses of the retrospective validation study (n = 40)
| Variable | Univariate Analysis (Log Rank Test), P | Multivariate Analysis (Cox Proportional Hazard Test), P |
|---|---|---|
| T stage (T12 vs T34) | .0009 | NS |
| Treatment method (chemoradiotherapy vs radiotherapy) | <.0001 | NS |
| Tumor volume before treatment (≥9000 mm3 vs <9000) | .0002 | .0217 |
| High ADC before treatment (≥0.86 vs <0.86) | <.0001 | .0001 |
a NS indicates P ≥ .05.
