Multivariate Cox Proportional Hazards Analysis of Factors Associated With Local Progression
| HR | 95% CI | P | |
|---|---|---|---|
| Treatment | |||
| RFA v SBRT | 3.84 | 1.62 to 9.09 | .002 |
| Age | 1.01 | 0.97 to 1.06 | .514 |
| Tumor size | 1.35 | 0.99 to 1.84 | .055 |
| Child-Pugh score | 0.95 | 0.74 to 1.22 | .703 |
| AFP | 1.12 | 0.97 to 1.30 | .130 |
| No. prior treatments | 1.25 | 1.00 to 1.56 | .055 |
NOTE. Age (per year), tumor size (per cm), Child-Pugh score (per point), AFP (per doubling) and No. prior treatments (per treatment) were treated as continuous variables.
Abbreviations: AFP, alpha-fetoprotein; HR, hazard ratio; RFA, radiofrequency ablation; SBRT, stereotactic body radiation therapy.
