Follow-up Information

There is no need for these data to updated periodically.

There is generally one observation for each participant in this follow-up project.

Data were collected in 1991 and 1992 by Dr. Lauren Whetstone.

The variable VISIT is, in fact, follow-up number. For this project, all should be either "1" or "2."

This information type is comparable to Visit Information, Information Type 000, in the traditional BLSA Master File.
