Table 3 Actuarial survival in patients with Budd Chiari syndrome treated by interventional radiology alone.

Baseline disease severity*	n	1 y survival (95% CI)	5 y survival (95% CI)
Class I	16	100%†	100%†
Class II	32	94% (86–100%)	86% (73–99%)
Class III	13	85% (65–100%)	77% (53–100%)

Overall, the difference in survival between all three classes was not significant (log rank test, p = 0.2). Difference in survival between classes I and III approached significance (log rank test, p = 0.062).

*Disease severity stratified using prognostic index described by Murad and colleagues.³ In a study of 237 patients with Budd Chiari syndrome, 117 of whom had surgical portosystemic shunts, they reported actuarial survival at one year of 93% (95% CI 86–100%) in class I, 85% (95% CI 78–92%) in class II, and 60% (95% CI 47–73%) in class III disease severity, and at five years 89% (95% CI 79–99%) in class I, 74% (95% CI 65–83%) in class II, and 42% (95% CI 28–56%) in class III disease severity, respectively.

†100% survival, so confidence intervals not available.
