Parameters of the relative survival analysis by using an additive model for cases of alveolar echinococcosis, University Hospital Zurich, Zurich, Switzerland, 1973–2022*

Characteristic Estimate 95% CI p value
Age at diagnosis 0.078 0.05–0.11 <0.0001
Year of diagnosis −0.018 −0.04 to 0.00 0.11
Sex, male vs. female 0.033 −0.47 to 0.53 0.90
Stage −0.036 −0.29 to 0.22 0.78
Surgery within 1 year −0.411 −0.93 to 0.10 0.12
Benzimidazole within 1 year −0.514 −1.13 to 0.10 0.10

*The additive survival model provides covariate estimates that reflect the direct effect of each covariate on the excess risk. Compared with a Cox proportional hazard, this effect is absolute and not exponential.
