a
Adjusted proportions based on multivariable logistic models controlling for number of conditions, age, sex, race/ethnicity, and education reported in eTable 8 in the Supplement.
b
P values are associated with the coefficients on number of conditions relative to 0 conditions and age relative to 18-59 y in these multivariable models.
