Dr Yablonski suggests that we adjust for the increased mortality rate
in nonusers of aspirin to determine the effect of aspirin on cataract formation
independent of its effect on mortality. Our analyses did adjust for differences
in follow-up time among study participants and thus would account for any
differences in mortality rates between users and nonusers of aspirin.
Concerning the issue of whether cataract is a marker for increased mortality,
follow-up for those participants who developed cataract was stopped on the
date of diagnosis; therefore, this issue does not seem relevant to the analysis.
