Table 2. Multivariate Cox regression analysis for overall survival prediction in the primary cohort.
| Variables | Clinic-radiological model | Combined model | |||
|---|---|---|---|---|---|
| Hazard ratios (95% CI) | P | Hazard ratios (95% CI) | P | ||
| BCLC stage | 2.62 (1.33–5.17) | 0.006 | 1.93 (0.91–4.12) | 0.09 | |
| Non-smooth tumor margin | 4.13 (1.29–13.26) | 0.02 | 2.84 (0.88–9.16) | 0.08 | |
| Combined rad-score | NA | NA | 2.61 (1.71–3.96) | <0.001 | |
The clinic-radiological model was built based on independent predictors without the addition of a radiomics signature. BCLC, Barcelona clinic liver cancer; CI, confidence interval; NA, not available.
