Variables in bold are significant at the <0.05 level
a
Racial discrimination is an ordinal variable measured as none, some/a little, a lot
b
Cigarette smoking status is coded as “never tried, tried never used regularly, former user, current user
c
C-reactive protein has been log transformed for normality
d
Obesity is BMI ≥ 30.
