More than half of British babies born with cystic fibrosis today will reach the age of 50, according to a new forecasting method.

The same is true of CF patients who have reached the age of 30 today, researchers said. Reaching 30 is a milestone that signals another 20 years of survival, the team said.

An article on the new forecasting method, and some of the predictions based on it, appeared in the Journal of Cystic Fibrosis. The title is “Up-to-date and projected estimates of survival for people with cystic fibrosis using baseline characteristics: A longitudinal study using UK patient registry data.”
