Kaplan-Meier curves including all entities. a 5-year overall survival (5-y OS) of all patients with and without migration background (n = 422). The mean OS was 34.8 months for the native German cohort (n = 211) and 30.8 months for the migration cohort (n = 211) (conditional logistic regression model; HR 0.951, 95% CI [0.670;1.349]; p = 0.771). b Progression-free survival (PFS) of all patients with and without a migration background (n = 422). The mean PFS was 23.5 months for the native German cohort (n = 211) and 22.5 months for the patients with migration cohort (n = 211) (HR 0.957, 95% CI [0.719;1.275]; p = 0.766). c Time to progression (TTP) of all patients with and without a migration background (n = 422). The mean TTP was 24.1 months for the native German cohort (n = 211) and 22.8 months for the migration cohort (n = 211) (conditional logistic regression model; HR 0.947, 95% CI [0.709;1.236]; p = 0.709)
