Table 4.
Multivariable analysis of overall survival (OS). Multivariable analysis was undertaken entering all variables associated with OS at the p < 0.05 level in univariate analysis and then applying a backward stepwise approach to retain significant factors at the p < 0.05 level in the final model.
| Variable | Multivariable Analysis | |
|---|---|---|
| HR (95% CI) | p-Value | |

| Ciliary body extension, present vs. absent | - | - |
| Disease-free interval (months), ≤24 vs. >24 | 2.7 (1.5–4.7) | <0.001 |
| Capsular miliary disease, present vs. absent | - | - |
| BAP1 mutation, present vs. absent | - | - |
| Cassoux classification, high vs. low | - | - |
| intermediate vs. low | - | - |
| TCGA classification, very high vs. high | - | - |
| intermediate vs. high | - | - |
| low vs. high | - | - |
| Chromosome 8q surgain, present vs. absent | 2.9 (1.6–5.2) | <0.001 |
