In Reply: Dr Hawes characterizes our sample
as geographically localized. Patients were initially seen at the same medical
center but had dispersed to 22 US states and Canada by the 50-year follow-up.
Concerning the representativeness of our control group, we sought volunteers
based on age and sex alone from 2 dermatology clinics, a walk-in senior center,
and the independent living unit of a retirement home. These are appropriate
venues considering the age of our sample.
