Age of subjects was determined at the death of the index case.
Viral markers and smoking status were determined at the first screen at which data were available for the index case.
The mean value was based on data from the screens attended by the index case.
Anti-Tax reactivity (+++, ++, +, and ±) was defined as positive; (−) as negative.
