Annual Mailers

Beginning in 1982, mailers were sent to all surviving RBS participants at approximately yearly intervals; the most recent mailer was in 2017.  To date, there have been 32 mailers in all, with response rates ranging from 65% to 93%. Mailers assessed a wide variety of information that varied from year to year, with many questions repeated in multiple mailers.  Detailed information on mailer data and a flowchart indicating the timing of the Annual Mailers relative to the Research Clinic Visits is available at the Annual Mailers tab.
