CRP C-reactive protein; IL-6 interleukin-6; SSSC subjective social status relative to others in the participant’s community; SSSUS subjective social status relative to others in the USA. Family-adjusted income was calculated as the midpoint of annual family income divided by the cubed root of the number of people living in the household.
