^*Means adjusted for age, sex, race, BMI, quartiles of the other inflammatory marker, and mean daytime diastolic BP

^†Means adjusted for age, sex, race, BMI, quartiles of the other inflammatory marker, and mean nighttime diastolic BP

^‡Means adjusted for age, sex, race, BMI, quartiles of the other inflammatory marker, and mean 24-hour diastolic BP

BMI = body mass index; BP = blood pressure; CRP = C-reactive protein; TNF-α = tumor necrosis factor-alpha
