How or where did they get the 13 years from ?

The study ended in 1999 (46+53)

" The study tracked 5,000 people born in 1946 throughout their lives
and who had completed the tests during home visits from specially
trained nurses at age 53."

Another 13 years waiting to see how many fell off their perches,
took it to 2012. Plus another two years gathering the data.
