| Predictor Variables | Overall Survival | |||
|---|---|---|---|---|
| Univariable Analysis | Multivariable Analysis | |||
| HR (95% CI) | p-Value | HR (95% CI) | p-Value | |
| Age | 1.01 (1.00–1.02) | 0.04 * | 1.03 (1.00–1.06) | 0.09 |
| Male (vs. female) | 0.78 (0.54–1.11) | 0.17 | NA | NA |
| SCC (vs. BCC) | 1.58 (0.92–2.72) | 0.10 | NA | NA |
| Melanoma (vs. BCC) | 1.90 (1.09–3.32) | 0.02 * | 2.88 (0.70–11.9) | 0.14 |
| Total (vs. Subtotal) OE | 1.25 (0.50–3.10) | 0.63 | NA | NA |
| Positive (vs. negative) margin | 2.39 (1.48–3.86) | <0.001 * | 2.04 (0.88–4.70) | 0.10 |
Variables mentioned in parenthesis were used as “bases” when running the Cox proportional hazards model. * Association is significant at the 0.05 level (two-tailed). Bold text denotes statistical significance. HR, hazard ratio; CI, confidence interval; SCC, squamous cell carcinoma; BCC, basal cell carcinoma; OE, orbital exenteration; NA, not applicable.
