Characteristics of the first-degree relatives and spouses of the cohort of Swedish patients with Wegener’s granulomatosis, and first-degree relatives and spouses of general population controls. Observed age distributions of the different generations are affected by truncation in the registers in which index persons born before 1932 can only contribute with offspring.
