At the age of 20 years, survival from the age of 10 was 59.1% for patients born in 1960-64, and 70.2% for those born in 1965-69; at 25 years, survival from the age of 10 was 40.7% in the 1960-64 cohort. Overall survival from birth for patients born in 1970-74 was 97.4% at 10 years, and 94.4% at 15 years. The most common cause of death was heart disease, followed by infection, liver disease, and malignancy.
