a
Adjusted perceived percentage based on multivariable ordinary least squares regressions reported in eTables 4-6 in the Supplement, which control for age, sex, race/ethnicity, and education.
b
P values are associated with the coefficients on number of conditions relative to 0 conditions and age relative to those aged 18 to 59 y.
c
Estimates are based on models that also include indicators for number of conditions.
d
P values are associated with the coefficients relative to having vs not having the given condition.
e
Estimates are based on analogous models but include indicators of specific conditions instead of number of conditions.
